The race detector on ppc64le corrupts command-line arguments lists if
they contain an empty string, and cmd/go often generates compiler
argument lists containing `-D ""`. Since this is equivalent to not
specifying the `-D` flag at all, just do that. This allows using a
race-detector-enabled cmd/compile on ppc64le.

FindFileNext sometimes returns a different mtime than looking at the
file directly, because the MFT on NTFS is written to lazily. In order to
keep these in sync, we use GetFileInformationByHandle to get the actual
mtime, and then write it back to the file explicitly.
Fixes#42637.

This CL backports a bunch of changes that landed on dev.typeparams,
but are not dependent on types2 or generics. By backporting, we reduce
the divergence between development branches, hopefully improving test
coverage and reducing risk of merge conflicts.

The VMOVQ instruction moves a 128-bit constant into a V register, as 128-bit
constant can't be loaded into a register directly, we split it into two 64-bit
constants and load it from constant pool. Currently we add the 128-bit constant
to literal pool by calling the 'addpool' function twice, this is not the right
way because it doesn't guarantee the two DWORD instructions are consecutive,
and the second call of addpool will overwrite the p.Pool field,resulting in a
wrong PC-relative offset value of the Prog.
This CL renames the flag LFROM3 to LFROM128, and adds a new function addpool128
to add a 128-bit constant to the literal pool.

This was removed in change 285692, however we need to explicitly pull libc.so

since we pull libc.so in via runtime/sys_openbsd2.go, however openbsd/arm64
does not do this currently.

In reflect.methodWrapper, we call escape analysis without including the
full batch of dependent functions, including the closure functions.
Because of this, we haven't created locations for the params/local
variables of a closure when we are processing a function that
inlines that closure. (Whereas in the normal compilation of the
function, we do call with the full batch.) To deal with this, I am
creating locations for the params/local variables of a closure when
needed.
Without this fix, the new test closure6.go would fail.

As with CL 285875, this required resolving some conflicts around
handling of //go:embed directives. Still further work is needed to
reject uses of //go:embed in files that don't import "embed", so this
is left as a TODO. (When this code was written for dev.typeparams, we
were still leaning towards not requiring the "embed" import.)
Also, the recent support for inlining closures (CL 283112) interacts
poorly with -G=3 mode. There are some known issues with this code
already (#43818), so for now this CL disables inlining of closures
when in -G=3 mode with a TODO to revisit this once closure inlining is
working fully.

Several of the bugs in #43818 are because we were not scanning the body
of an possibly inlined closure in tooHairy(). I think this scanning got
lost in the rebase past some of the ir changes. This fixes the issue
related to the SELRECV2 and the bug reported from cuonglm. There is at
least one other bug related to escape analysis which I'll fix in another
change.

In msan mode we instrument code with msan* functions, including
msanmove. In some configurations the code is instrumented by the
compiler but msan is not actually linked in, so we need dummy
definitions for those functions so the program links. msanmove is
newly added in CL 270859 but a dummy definition in msan0.go was
not added, causing link failures. Add it.

In the signal handler, we adjust gsingal's stack to the stack
where the signal is delivered. TSAN may deliver signals to the
g0 stack, so we have a special case for the g0 stack. However,
we don't have very good accuracy in determining the g0 stack's
bounds, as it is system allocated and we don't know where it is
exactly. If g0.stack.lo is too low, the condition may be
triggered incorrectly, where we thought the signal is delivered to
the g0 stack but it is actually not. In this case, as the stack
bounds is actually wrong, when the stack grows, it may go below
the (inaccurate) lower bound, causing "morestack on gsignal"
crash.
Check for g0 stack last to avoid this situation. There could still
be false positives, but for those cases we'll crash either way.
(If we could in some way determine the g0 stack bounds accurately,
this would not matter (but probably doesn't hurt).)

Previously, if CC was a path without separators (like gcc or clang),
we'd look it up in PATH in cmd/go using internal/execabs.LookPath,
then pass the resolved path to cgo in CC.
This caused a regression: if the directory in PATH containing CC has a
space, cgo splits it and interprets it as multiple arguments.
With this change, cmd/go no longer resolves CC before invoking
cgo. cgo does the path lookup on each invocation. This reverts the
security fix CL 284780, but that was redundant with the addition of
internal/execabs (CL 955304), which still protects us.

This merge had two conflicts to resolve:
1. The embed code on master had somewhat substantially diverged, so
this CL tediously backported the changes to dev.regabi. In particular,
I went through all of the embed changes to gc/{embed,noder,syntax}.go
and made sure the analogous code on dev.regabi in noder/noder.go and
staticdata/embed.go mirrors it.
2. The init-cycle reporting code on master was extended slightly to
track already visited declarations to avoid exponential behavior. The
same fix is applied on dev.regabi, just using ir.NameSet instead of
map[ir.Node]bool.

The previous code was stylized after noder, which was written when it
was more idiomatic to simple create a gc.Node and then populate and
shuffle around its fields as appropriate.
Now with package ir, it's somewhat nicer to compute all the fields up
front and pass them to the constructor functions, rather than passing
nil and populating the fields afterwards.
Net addition of lines of code, but I think the new code is overall
still somewhat simpler, and will be easier to refactor out into code
for helpers.go.

The types2.Config.IgnoreBranches flag mistakenly excluded a
set of label-unrelated branch checks. After fixing this and
also adjusting some error messages to match the existing
compiler errors, more errorcheck tests pass now with the -G

checks.

Introduces a wrapper around os/exec, internal/execabs, for use in
all commands. This wrapper prevents exec.LookPath and exec.Command from
running executables in the current directory.
All imports of os/exec in non-test files in cmd/ are replaced with
imports of internal/execabs.
