Update stdarch submodule (to before it switched to const generics)

This also includes a cherry-pick of
ec1461905b
and https://github.com/rust-lang/stdarch/pull/1108 to fix a build
failure.

It also adds a re-export of various macros to the crate root of libstd -
previously they would show up automatically because std_detect was defined
in the same crate.
