Previously we expected the default GODEBUG that's embedded in the binary
to be taken into account for build actionIDs through the build info. The
build info contains the default GODEBUG for a package main, and then
that build info is used to generate the action id. But tests of packages
other than main do not have buildinfo set on them. So the default
GODEBUG isn't taken into account in the action id for those tests.
Explicitly include GODEBUG when generating all link actions' action ids
to make sure it's always present.

asm_riscv64.h will be used to define macros for each riscv64
extension that is not part of the rva20u64 base profile but that the
_riscv64.s assembly files are allowed to use because the user has
specified a more capable profile in the GORISCV64 variable. This will
allow us, for example, to test for the hasZba macro in those assembly
files instead of the GORISCV64_rva22u64 macro before using a Zba
instruction. This is important as it means that in the future when
we add support for new profiles that support Zba, e.g., rva23u64,
we only need to update asm_riscv64.h to indicate rva23u64 supports
Zba. We will not need to update every assembly language file that
already uses Zba instructions.

Use OTAILCALL in wrapper if the receiver and method are both pointers and it is
not going to be inlined, similar to how it is done in reflectdata.methodWrapper.
Currently tail call may be used for functions with identical argument types.
This change updates wrappers where both wrapper and the wrapped method's
receiver are pointers. In this case, we have the same signature for the
wrapper and the wrapped method (modulo the receiver's pointed-to types),
and do not need any local variables in the generated wrapper (on stack)
because the arguments are immediately passed to the wrapped method in place
(without need to move some value passed to other register or to change any
argument/return passed through stack). Thus, the wrapper does not need its
own stack frame.
This applies to promoted methods, e.g. when we have some struct type U with
an embedded type *T and construct a wrapper like
func (recv *U) M(arg int) bool { return recv.T.M(i) }
See also test/abi/method_wrapper.go for a running example.

There is the expectation that if 'go telemetry off' is run with a clean
home directory that no counter files are written. But we were writing
counters in that case because the act of turning telemetry off was done
after the act of opening the counter files, so the counter files were
opened depending on what the previous mode was. Add a special check that
the command is not 'go telemetry off' before opening counter files.

On Android, faccessat2 syscall (which supports flags like AT_EACCESS) is
not allowed, so syscall.Faccessat tries to emulate AT_EACCESS check in
userspace using os.Stat, os.Geteuid etc.
Also, according to [1],
> Android doesn't have setuid programs, and never runs code with euid!=uid.
This means on Android the proper AT_EACCESS check is neither possible
nor really needed.
Let's skip the syscall.Faccessat userspace emulation of AT_EACCESS
check and return ENOSYS, so the callers can use a fallback.
This should speed up exec.LookPath on Android.

Eaccess, initially added by CL 414824 for linux only, was later
implemented for freebsd (CL 531155), netbsd (CL 531876), dragonfly
(CL 532675), openbsd (CL 538836), and darwin (CL 579976).
The only unix platforms which lack Eaccess are Solaris/Illumos and AIX.
For AIX, syscall.Faccessat is already available, the only missing piece
was AT_EACCESS constant. Let's take it from [1], which, judging by a few
other known AT_ constants, appears to be accurate.
For Solaris, wire the faccessat using the same logic as in the syscall
package.
Now, when we have faccessat for every unix, we can drop eaccess_other.go
and consolidate Eaccess implementations to use faccessat.

Function stdlibImportcfgFile creates a temporary directory and a file in
it, which are never deleted.
The easiest to fix this (without creating the file unnecessarily, or
creating it multiple times) is to add a global tmpDir and use it in
stdlibImportcfgFile.

Generally, the parser strips (i.e., does not record in the syntax tree)
unnecessary parentheses. Specifically, given a type parameter list of
the form
[P (C),]
it records it as
[P C]
and then no comma is required when printing. However it did only strip
one level of parentheses, and
[P ((C)),]
made it through, causing a panic when printing. Somewhat related,
the printer stripped parentheses around constraints as well.
This CL implements a more consistent behavior:
1) The parser strips all parentheses around constraints. For testing
purposes, a local flag (keep_parens) can be set to retain the
parentheses.
2) The printer code now correctly intruces a comma if parentheses
are present (e.g., when testing with keep_parens). This case does
not occur in normal operation.
3) The printer does not strip parentheses around constraints since
the parser does it already.
For #69206.

This implementation utilizes the same registers found in the reference
implementation, aiming to produce a minimal semantic diff between the
Avo-generated output and the original hand-written assembly.
To verify the Avo implementation, the reference and Avo-generated
assembly files are fed to `go tool asm`, capturing the debug output into
corresponding temp files. The debug output contains supplementary
metadata (line numbers, instruction offsets, and source file references)
