Issue #61486 causes a compiler crash but is not detected when running
stand-alone type-checker tests because no types are recorded.
Set up Config.Info map with all maps when when running local tests
so that type/object recording code is executed during local tests.

Currently we may pass C linker flags in nondeterministic order,
as on ELf systems we pass --export-dynamic-symbol for symbols from
a map. This is usally not a big problem because even if the flags
are passed in nondeterministic order the resulting binary is
probably still deterministic. This CL makes it pass them in a
deterministic order to be extra sure. This also helps build
systems where e.g. there is a build cache for the C linking action.

When running "go test" including a main package which has a PGO
profile, we currently build the package being tested and its
dependencies with PGO, but we failed to attach the profile to
test-only dependencies. If a package is (transitively) imported
by both the package being tested and the test, the PGO version
and the non-PGO version of the package are both linked into the
binary, causing link-time error.
This CL fixes this by attaching the PGO profile to dependencies of
the test.
Fixes#61376.

Currently, on darwin, we only support cgo_dynamic_import for
functions, but not variables, as we don't need it before.
mach_task_self_ is a variable defined in the system library, which
can be used to e.g. access the process's memory mappings via the
mach API. The C header defines a macro mach_task_self(), which
refers to the variable. To use mach_task_self_ (in pure-Go
programs) we need to access it in Go.
This CL handles cgo_dynamic_import for variables in the linker,
loading its address via the GOT. (Currently only on Darwin, as
we only need it there.)

The runtime was adjusting netpollWaiters before the waiting
goroutines were marked as ready. This could cause the scheduler
to report a deadlock because there were no goroutines ready to run.
Keeping netpollWaiters non-zero ensures that at least one goroutine
will call netpoll(-1) from findRunnable.
This does mean that if a program has network activity for a while
and then never has it again, and also has no timers, then we can leave
an M stranded in a call to netpoll from which it will never return.
At least this won't be a common case. And it's not new; this has been
a potential problem for some time.

The Windows DLL loader may call a DLL entry point, in our case
_rt0_amd64_windows_lib, with a stack that is
not 16-byte aligned. In theory, it shouldn't, but under some
circumstances, it does (see below how to reproduce it).
Having an unaligned stack can, and probably will, cause problems
down the line, for example if a movaps instruction tries to store
a value in an unaligned address it throws an Access Violation exception
(code 0xc0000005).
I managed to consistently reproduce this issue by loading a Go DLL into
