Mostly this is using uint32 instead of int32 for unsigned values
like instruction encodings or float32 bit representations,
removal of ternary operations, and removal of #defines.
Delete sched9.c, because it is not compiled (it is still in the history
if we ever need it).

640 bytes ought to be enough for anybody.
We'll bring this back down before Go 1.5. That's issue 9214.

The conversion was done with an automated tool and then
modified only as necessary to make it compile and run.
[This CL is part of the removal of C code from package runtime.
See golang.org/s/dev.cc for an overview.]

It will be 8K on windows because it needs 4K for the OS.
Similarly, plan9 will be 4K.
On linux/amd64, reduces size of 100,000 goroutines
from ~819MB to ~245MB.
Update #7514

Commit to stack copying for stack growth.
We're carrying around a surprising amount of cruft from older schemes.
I am confident that precise stack scans and stack copying are here to stay.
Delete fallback code for when precise stack info is disabled.
Delete fallback code for when copying stacks is disabled.
Delete fallback code for when StackCopyAlways is disabled.
Delete Stktop chain - there is only one stack segment now.
Delete M.moreargp, M.moreargsize, M.moreframesize, M.cret.
Delete G.writenbuf (unrelated, just dead).
Delete runtime.lessstack, runtime.oldstack.
Delete many amd64 morestack variants.
Delete initialization of morestack frame/arg sizes (shortens split prologue!).
Replace G's stackguard/stackbase/stack0/stacksize/
syscallstack/syscallguard/forkstackguard with simple stack
bounds (lo, hi).
Update liblink, runtime/cgo for adjustments to G.

Preparation was in CL 134570043.
This CL contains only the effect of 'hg mv src/pkg/* src'.
