If the user requests the 'all' pattern in addition to explicit roots
outside of 'all', we should not load the transitive dependencies of
those explicit roots as if they were *in* 'all'. Without the '-test'
flag, we should not load test dependencies of any package outside of
'all'. Even *with* the '-test' flag, we should only load test
dependencies of the requested roots, not test dependencies of other
packages that happen to be imported by those roots.
More precise tracking of membership in 'all' will be important when we
implement lazy loading, because membership in 'all' determines which
module dependencies we will record in the main module's go.mod file.
This change also reduces reliance on global state, factors out the
loading process into several smaller functions, and sets us up to
reuse the 'go mod vendor' version of the 'all' pattern for lazy
loading.

Both ReadMemStatsSlow and CheckScavengedBits iterate over the page
allocator's chunks but don't actually check if they exist. During the
development process the chunks index became sparse, so now this was a
possibility. If the runtime tests' heap is sparse we might end up
segfaulting in either one of these functions, though this will generally
be very rare.
The pattern here to return nil for a nonexistent chunk is also useful
elsewhere, so this change introduces tryChunkOf which won't throw, but
might return nil. It also updates the documentation of chunkOf.

Currently, the statement:

runtime.KeepAlive(tmp)
which doesn't guarantee that tmp is still alive by time the g call is
scheduled to run.
This CL fixes the issue, by wrapping g call in a closure:
go func(p unsafe.Pointer) {
g(uintptr(p))
}(f())
then this will be rewritten into:
tmp := f()
go func(p unsafe.Pointer) {
g(uintptr(p))

}(tmp)
runtime.KeepAlive(tmp) // superfluous, but harmless
So the unsafe.Pointer p will be kept alive at the time g call runs.

On darwin, with external linking, the system linker produces STAB
(symbolic debugging) symbols in the binary's symbol table. These
include paths of the intermediate object files, like
<tmpdir>/go.o, which changes from run to run, making the build
non-reproducible.
Since we run dsymutil to produce debug info and combine them
back into the binary, we don't need those STAB symbols anymore.
Strip them after running dsymutil.
If DWARF is not enabled, we don't run dsymutil. We can pass
"-Wl,-S" to let the system linker not generate those symbols.
While here, also make it more consistent about DWARF combining.
Currently we only do DWARF combining on macOS/AMD64, when DWARF

This defines a macro for the regabi GOEXPERIMENT when assembling

In general, assembly code will be shielded from the calling convention
change, but there is a small amount of runtime assembly that is going
to have to change. By defining a macro, we can easily make the small
necessary changes. The other option is to use build tags, but that
would require duplicating nontrivial amounts of unaffected code,
leading to potential divergence issues. (And unlike Go code, assembly
code can't depend on the compiler optimizing away branches on a
feature constant.) We consider the macro preferable, especially since
this is expected to be temporary as we transition to the new calling
convention.

While debugging #40771, I realized that the chatty printer should only
ever print to a single io.Writer (normally os.Stdout). The other
Writer implementations in the chain write to local buffers, but if we
wrote a test's output to a local buffer, then we did *not* write it to
stdout and we should not store it as the most recently logged test.
Because the chatty printer should only ever print to one place, it
shouldn't receive an io.Writer as an argument — rather, it shouldn't
be used at all for destinations other than the main output stream.
On the other hand, when we flush the output buffer to stdout in the
top-level flushToParent call, it is important that we not allow some
other test's output to intrude between the test summary header and the
remainder of the test's output. cmd/test2json doesn't know how to
parse such an intrusion, and it's confusing to humans too.
No test because I couldn't reproduce the user-reported error without
modifying the testing package. (This behavior seems to be very
sensitive to output size and/or goroutine scheduling.)

This pulls in golang.org/cl/250920 which rejects Windows shortnames as
path components in module.CheckImportPath (as is already done in
cmd/go/internal/get's copy of CheckImportPath). This will allow us to replace
the copy of CheckImportPath with the original.
This also pulls in golang.org/cl/250919 which rejects + in CheckPath and
CheckImportPath, and golang.org/cl/235597, which adds methods to the zip
package for gorelease, but shouldn't affect cmd.
This change also updates the cmd/go test case TestScript/mod_bad_filenames
to reflect that golang.org/x/mod/zip error messages now include filenames
for bad file names that can't be included in zip archives.
Updates #29101
