Shorten some of the longest tests that run during all.bash.
Removes 7r 50u 21s from all.bash.
After this change, all.bash is under 5 minutes again on my laptop.
For #26473.

This change adds support in testing/quick to generate maps and slices
in additional states:
(1.) nil maps
(2.) nil slices
(3.) empty slice occupancy: `len(s) == 0 && s != nil`
(4.) partial slice occupancy: `len(s) < cap(s) && s != nil`
(5.) full slice occupancy: `len(s) == cap(s) && s != nil`
Prior to this, only #5 was ever generated, thereby not sufficiently
exercising all of the fuzzable code path outcomes.
This change depends on https://go-review.googlesource.com/#/c/17499/.

Recursive types R containing slices of R's did not terminate despite the
effort in CL 10821.
For recursive types there was a competition between slice expansion by a
factor 'complexSize', and termination with probability '1/complexSize'
which lead to stack overflow as soon as a recursive struct had slices
pointing to its own type.
Fix this by shrinking the size hint as a function of recursion depth.
This has the dual effect of reducing the number of elements generated
per slice and also increasing the probability for termination.
Fixes #11148.

The documentation for quick.Value says that it "returns an arbitrary
value of the given type." In spite of this, nil values for pointers were
never generated, which seems more like an oversight than an intentional
choice.
The lack of nil values meant that testing recursive type like
type Node struct {
Next *Node
}
with testing/quick would lead to a stack overflow since the data
structure would never terminate.
This change may break tests that don't check for nil with pointers
returned from quick.Value. Two such instances were found in the standard
library, one of which was in the testing/quick package itself.
Fixes #8818.

This commit is largely cosmetic in the sense that it is the remnants
of a change proposal I had prepared for testing/quick, until I
discovered that 3e9ed27 already implemented the feature I was looking
for: quick.Value() for reflect.Kind Array. What you see is a merger
and manual cleanup; the cosmetic cleanups are as follows:
(1.) Keeping the TestCheckEqual and its associated input functions
in the same order as type kinds defined in reflect.Kind. Since
3e9ed27 was committed, the test case began to diverge from the
constant's ordering.
(2.) The `Intptr` derivatives existed to exercise quick.Value with
reflect.Kind's `Ptr` constant. All `Intptr` (unrelated to `uintptr`)
in the test have been migrated to ensure the parallelism of the
listings and to convey that `Intptr` is not special.
(3.) Correct a misspelling (transposition) of "alias", whereby it is
named as "Alais".

Generating array types like [4]int would fail even though the int type
is generatable. Allow generating values of array types when the inner
type is generatable.
