This adds the _lib entry point to various GOOS_amd64.s files.
A future CL will enable c-archive/c-shared mode for those targets.
As far as I can tell, the newosproc0 function in os_darwin.go was
passing the wrong arguments to bsdthread_create. The newosproc0
function is never called in the current testsuite.

All of the amd64 entry point code is the same except for Plan 9.
Unify it all into asm_amd64.s.

Android's libc doesn't provide access to auxv, so currently the Go
runtime synthesizes a fake, minimal auxv when loaded as a library on
Android. This used to be sufficient, but now we depend on auxv to
retrieve the system physical page size and panic if we can't retrieve
it.
Fix this by falling back to reading auxv from /proc/self/auxv if the
loader-provided auxv is empty and removing the synthetic auxv vectors.
Fixes #18041.

Android linker does not handle TLS for us. We set up the TLS slot
for g, as darwin/386,amd64 handle instead. This is disgusting and
fragile. We will eventually fix this ugly hack by taking advantage
of the recent TLS IE model implementation. (Instead of referencing
an GOT entry, make the code sequence look into the TLS variable that
holds the offset.)
The TLS slot for g in android/amd64 assumes a fixed offset from %fs.
See runtime/cgo/gcc_android_amd64.c for details.
