HasExec is an attractive nuisance: it is tempting to check in a
TestMain function, but TestMain really shouldn't be running
subprocesses eagerly anyway (they add needless overhead for operations
like 'go test -list=.'), and the trick of re-executing the test binary
to determine whether 'exec' works ends up in infinite recursion if
TestMain itself calls HasExec.
Instead, tests that need to execute a subprocess should call
MustHaveExec or MustHaveExecPath from within a specific test,
or just try to exec the program and check its error status
(perhaps using testenv.SyscallIsNotSupported).
While I'm in here and testing on the SlowBots anyway, a few other
cleanups relating to subprocesses:
- Add more t.Helper calls to support checks where appropriate.
- Remove findGoTool, which can be simplified to exec.LookPath as of
CL 404134.
- Add tests confirming the expected behavior of the support functions
on the Go project's builders.

go_android_exec gets the exit status of the process run inside the
Android emulator by sending a small shell script that runs the desired
command and then prints "exitcode=" followed by the exit code. This is
necessary because adb does not reliably pass through the exit status
of the subprocess.
An old bug about this
(https://code.google.com/p/android/issues/detail?id=3254) was closed
in 2016 as fixed in Android N (7.0), but it seems that the adb on the
Android builder at least still sometimes fails to pass through the
exit code.
Unfortunately, this workaround has the effect of injecting
"exitcode=N" into the output of the subprocess it runs, which messes
up tests that are looking for golden output from a subprocess.
Fix this by inserting a filter Writer that looks for the final
"exitcode=N" and strips it from the exec wrapper's own stdout.

For this test, it turns out that the HasExec check is redundant
anyway: if we can exec 'go build', we can certainly exec programs in

Angle brackets should not appear in CSS contexts, as they may affect
token boundaries (such as closing a <style> tag, resulting in
injection). Instead emit filterFailsafe, matching the behavior for other
dangerous characters.

Re-enable frame pointer unwinding for execution tracing on amd64 by
default, now that CL 489015 and CL 488755 have fixed recently-discovered
crashes. This reverts CL 486382.
These fixes, together with CL 241158 to fix up frame pointers when
copying stacks on arm64, also make frame pointer unwinding for tracing
safe to enable for arm64. This should significantly reduce the CPU and
latency overhead of execution tracing on arm64, as it has for amd64.

This change causes cgo to emit an error (with the same
message as the compiler) when it encounters a declaration
of a method whose receiver type is C.T or *C.T.
Conceptually, C is another package, but unfortunately
the desugaring of C.T is a type within the same package,
causing the previous behavior to accept invalid input.
It is likely that at least some users are intentionally
exploiting this behavior, so this may break their build.
We should mention it in the release notes.

Some versions of dsymutils, notably the one in clang 14.0.3, which
is shipped in some versions of Xcode, have a bug that it creates a
temporary directory but doesn't clean it up at exit. The temporary
directory is created in DSYMUTIL_REPRODUCER_PATH (if set,
otherwise TMPDIR). Work around the issue by setting
DSYMUTIL_REPRODUCER_PATH to the linker's temporary directory, so
the linker will clean it up at exit anyway.
Fixes#59026.
