Unified IR added several new IR fields for holding *runtime._type
expressions. To avoid throwing off any frontend semantics
(particularly inlining cost heuristics), they were marked as
`mknode:"-"` so that code wouldn't visit them.
Unfortunately, this has a bad interaction with the static init
inlining optimization, because the latter relies on ir.EditChildren to
substitute all parameters. This potentially includes dictionary
parameters, which can appear within the new RType fields.
This CL adds a new ir.EditChildrenWithHidden function that also edits
these fields, and switches staticinit to use it. Longer term, we
should unhide the RType fields so that ir.EditChildren visits them
normally, but that's scarier so late in the release cycle.
Fixes #57778.

OIOTA used to be used to represent "iota" in the pre-typechecked IR,
before we knew whether it was safe to replace it with a constant
(because it could be redefined as a global symbol later).
However, now types2 handles constant folding, including handling of
"iota". So this can go away.

The typechecking code for dealing with dot imports and redeclaration
errors can be removed, as these will now always be caught by types2
instead. Even when running the typecheck on internally constructed IR,
we'll never introduce new imports or redeclare identifiers.
Also, Func.Shortname (and typecheck.addmethod) was only used by the
-G=0 frontend. The new types2-based frontends directly associate
methods with their receiver type during IR construction.

With the switch to the register ABI, we now generate wrapper
functions for go statements in many cases. A new goroutine's start
PC now points to the wrapper function. This does not affect
execution, but the runtime tracer uses the start PC and the
function name as the name/label of that goroutine. If the start
function is a named function, using the name of the wrapper loses
that information. Furthur, the tracer's goroutine view groups
goroutines by start PC. For multiple go statements with the same
callee, they are grouped together. With the wrappers, which is
context-dependent as it is a closure, they are no longer grouped.
This CL fixes the problem by providing the underlying unwrapped
PC for tracing. The compiler emits metadata to link the unwrapped
PC to the wrapper function. And the runtime reads that metadata
and record that unwrapped PC for tracing.
(This doesn't work for shared buildmode. Unfortunate.)

C/C++ address sanitizer. Every memory read/write will be replaced
by a call to asanread/asanwrite.
This CL also inserts asan instrumentation during SSA building.
This CL passes tests but is not usable by itself. The actual
implementation of asanread/asanwrite in the runtime package, and
support for -asan in the go tool and tests, will follow in subsequent
CLs.

Currently, for hidden closures, we always push them to compile queue
during typechecking. If the hidden closure is discarded from the outer
function body during deadcode, any desugaring phase after deadcode won't
be applied to the closure. Thus, some un-expected OPs are passed to
downstream passes, which they can't handle, the compiler goes boom!
To fix this, we keep track of discarded hidden closures during deadcode
pass, and won't compile them then.

The Func.ClosureCalled flag is an optimization used by escape analysis
to detect closures that were directly called, so we know we have
visibility of the result flows. It's not needed by any other phases of
the compiler, so we might as well calculate it within escape analysis
too.
This saves some trouble during IR construction and trying to maintain
the ClosureCalled flag through inlining and copying.

This CL moves two bits of related code from order.go to escape
analysis:
1. The recognition of "unsafe uintptr" arguments passed to
syscall-like functions.
2. The wrapping of go/defer function calls in parameter-free function
literals.
As with previous CLs, it would be nice to push this logic even further
forward, but for now escape analysis seems most pragmatic.
A couple side benefits:
1. It allows getting rid of the uintptrEscapesHack kludge.
2. When inserting wrappers, we can move some expressions into the
wrapper and escape analyze them better. For example, the test
expectation changes are all due to slice literals in go/defer calls
where the slice is now constructed at the call site, and can now be
stack allocated.

I initially made NewClosureFunc take an "outerfn *Func" parameter
because I was planning on having it handle closure naming, until
remembering that naming needs to wait until typecheck for noder.
We don't actually need the *Func yet, just to know whether it's
non-nil. So change the parameter to a bool, which simplifies callers a
little.

typecheck.tcClosure is complicated with many code flows because all of
its callers setup the closure funcs in slightly different ways. E.g.,
it's non-obvious who's responsible for setting the underlying func's
Sym or adding it to target.Decls, or how to write new code that
constructs a closure without interfering with existing code.
This CL refactors everything to use three common functions in package
ir: NewClosureFunc (which handle creating the Func, Name, and
ClosureExpr and wiring them together), NameClosure (which generates
and assigns its unique Sym), and UseClosure (which handles adding the
Func to target.Decls).
Most IR builders can actually name the closure right away, but the
legacy noder+typecheck path may not yet know the name of the enclosing
function. In particular, for methods declared with aliased receiver
parameters, we need to wait until after typechecking top-level
declarations to know the method's true name. So they're left anonymous
until typecheck.
UseClosure does relatively little work today, but it serves as a
useful spot to check that the code setting up closures got it right.
It may also eventually serve as an optimization point for early
lifting of trivial closures, which may or may not ultimately be
beneficial.

When compiling runtime, we don't allow closures to escape,
because we don't want (implicit) allocations to occur when it is
not okay to allocate (e.g. in the allocator itself). However, for
go statement, it already allocates a new goroutine anyway. It is
okay to allocate the closure. Allow it.
Also include the closure's name when reporting error.

This CL refactors mkinlcall by extracting the core InlinedCallExpr
construction code into a new "oldInline" function, and adds a new
"NewInline" hook point that can be overriden with a new inliner
implementation that only needs to worry about the details of
constructing the InlinedCallExpr.
It also moves the delayretvars optimization check into CanInline, so
it's performed just once per inlinable function rather than once for
each inlined call.
Finally, it skips printing the function body about to be inlined (and
updates the couple of regress tests that expected this output). We
already report the inline body as it was saved, and this diagnostic is
only applicable to the current inliner, which clones existing function
body instances. In the unified IR inliner, we'll directly construct
inline bodies from the serialized representation.

This CL restructures how we track function ABIs and generate ABI
wrappers in the compiler and adds import/export of ABIs across package
boundaries.
Currently, we start by tracking definition and referencing ABIs in two
global maps and eventually move some of this information into the
LSyms for functions. This complicates a lot of the existing code for
handling wrappers and makes it particularly hard to export ABI
information across packages. This change is built around instead
recording this information on the ir.Func.
First, this change replaces the global ABI def/ref maps with a type,
which makes the data flow and lifetime of this information clear in
gc.Main. These are populated during flag parsing.
Then, early in the front-end, we loop over all ir.Funcs to 1. attach
ABI def/ref information to the ir.Funcs and 2. create new ir.Funcs for
ABI wrappers. Step 1 is slightly subtle because the information is
keyed by linker symbol names, so we can't simply look things up in the
compiler's regular symbol table.
By generating ABI wrappers early in the front-end, we decouple this
step from LSym creation, which makes LSym creation much simpler (like
it was before ABI wrappers). In particular, LSyms for wrappers are now
created at the same time as all other functions instead of by
makeABIWrapper, which means we're back to the simpler, old situation
where InitLSym was the only thing responsible for constructing
function LSyms. Hence, we can restore the check that InitLSym is
called exactly once per function.
Attaching the ABI information to the ir.Func has several follow-on
benefits:
1. It's now easy to include in the export info. This enables direct
cross-package cross-ABI calls, which are important for the performance
of calling various hot assembly functions (e.g., internal/bytealg.*).
This was really the point of this whole change.
2. Since all Funcs, including wrappers, now record their definition
ABI, callTargetLSym no longer needs to distinguish wrappers from
non-wrappers, so it's now nearly trivial (it would be completely
trivial except that it has to work around a handful of cases where
ir.Name.Func is nil).
The simplification of callTargetLSym has one desirable but potentially
surprising side-effect: the compiler will now generate direct calls to
the definition ABI even when ABI wrappers are turned off. This is
almost completely unnoticeable except that cmd/internal/obj/wasm looks
for the call from runtime.deferreturn (defined in Go) to
runtime.jmpdefer (defined in assembly) to compile is specially. That
now looks like a direct call to ABI0 rather than going through the
ABIInternal alias.
While we're in here, we also set up the structures to support more
than just ABI0 and ABIInternal and add various additional consistency
checks all around.
Performance-wise, this reduces the overhead induced by wrappers from
1.24% geomean (on Sweet) to 0.52% geomean, and reduces the number of
benchmarks impacts >2% from 5 to 3. It has no impact on compiler speed.

CL 64811 removed dcopy. Update the comment in types.Sym.
The Russquake moved iexport.go. Update the path to it.
WRAPPER is now also used by ABI wrappers, so update the comment since
it's now more general than method wrappers.

Currently there's a lot of logic within package types for creating
Linksyms. This CL pulls it out into base, where it can be more easily
reused by other compiler code that shouldn't need to depend on package
types.
Package base probably isn't the best place for this, but it's
convenient because it's a package that types already depends on. It's
also where the Ctxt object lives, which these functions depend upon.

This CL reorders function compilation to ensure that functions are
always compiled before any enclosed function literals. The primary
goal of this is to reduce the risk of race conditions that arise due
to compilation of function literals needing to inspect data from their
closure variables. However, a pleasant side effect is that it allows
skipping the redundant, separate compilation of function literals that
were inlined into their enclosing function.

Historically, inline function bodies were exported as plain Go source
code, and symbol mangling was a convenient hack because it allowed
variables to be re-imported with largely the same names as they were
originally exported as.
However, nowadays we use a binary format that's more easily extended,
so we can simply serialize all of a function's declared objects up
front, and then refer to them by index later on. This also allows us
to easily report unmangled names all the time (e.g., error message
from issue7921.go).
Fixes #43633.

After using the IR visitor code for a bit, it seems clear that a
simple boolean result type is adequate for tree traversals. This CL
updates ir.DoChildren to use the same calling convention as ir.Any,
and updates mknode.go to generate code accordingly.
There were only two places where the error-based DoChildren API was
used within the compiler:
1. Within typechecking, marking statements that contain "break". This
code never returns errors anyway, so it's trivially updated to return
false instead.
2. Within inlining, the "hairy visitor" actually does make use of
returning errors. However, it threads through a reference to the
hairyVisitor anyway, where it would be trivial to store any needed
information instead. For the purpose of this CL, we provide
"errChildren" and "errList" helper functions that provide the previous
error-based semantics on top of the new bool-based API.

This CL generalizes ir/mknode.go to get rid of most of almost all of
its special cases for node field types. The only remaining speciale
case now is Field, which doesn't implement Node any more, but perhaps
should.
To help with removing special cases, node fields can now be tagged
with `mknode:"-"` so that mknode ignores them when generating its
helper methods. Further, to simplify skipping all of the orig fields,
a new origNode helper type is added which declares an orig field
marked as `mknode:"-"` and also provides the Orig and SetOrig methods
needed to implement the OrigNode interface.

Two simplifications:
1. Statements (including ODCLFUNC) don't have types, and the
Func.Nname already has a type. There's no need for a second one.
However, there is a lot of code that expects to be able to call
Func.Type, so leave a forwarding method, like with Sym and Linksym.
2. Inline and remove ir.NewFuncNameAt. It doesn't really save any
code, and it's only used a handful of places.

Syms are meant to be just interned (pkg, name) tuples, and are a
purely abstract, Go-language concept. As such, associating them with
linker symbols (a low-level, implementation-oriented detail) is
inappropriate.
There's still work to be done before linker symbols can be directly
attached to their appropriate, higher-level objects instead. But in
the mean-time, we can at least add helper functions and discourage
folks from using Sym.Linksym directly. The next CL will mechanically
rewrite code to use these helpers where possible.

Sets up for removing Func from Node interface.
That means that once the Name reorg is done,
which will let us remove Name, Sym, and Val,
Node will be basically a minimal interface.

Ending typecheck1 in the switch makes it safe for each case
to do an appropriate type assertion. The main change is dropping
the computation of "ok" and using the syntax nodes themselves
to decide what's OK.

RawCopy breaks the invariant that ir.Orig depends on for
allowing nodes to omit keeping their own orig fields.
Avoid surprises by unexporting it.
The only use in package gc was removed in the previous CL.
This one is a straight global search and replace RawCopy -> rawCopy.
