libgo: add "vendor" to pkgpath for vendored standard packages
Ensure that the packages vendored into the standard library do not
have the same pkgpath as the actual packages. If we don't, attempts
to build and test the actual packages will get confused. The specific
error I was seeing was import loops, causing some of the packages to
fail to get initialized, causing an obscure run time crash.

This patch fixes the regression caused by the changes to add square root
estimation when compiling for xgene-1 or exynos-m1 targets.
The issue is that the expand path for the reciprocal estimate square
root pattern assumes that pattern cannot fail once it has been decided
that this expansion path is available, but because the logic deep inside
aarch64_emit_approx_sqrt() differs from use_rsqrt_p() the two disagree
as to what is safe.
This patch refactors the logic to ensure that we cannot unknowingly make
different choices here.

This patch changes the parameter testing for powerpc vector builtins to relax
the existing requirement that the parameters be identical to instead that they
be compatible. This allows for mixing parameters with differing qualified
(const, volatile, etc.) types.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80482 for more information.

able to handle const_wide_int yet. It works with predicates so the
