Add mempcpy implementation
A GNU extension that returns dst + size instead of dst. It's a nice
shortcut when copying strings with a known size or back-to-back blocks
and you have to do it often.
May of course be called directly or alternately through
__builtin_mempcpy in some compiler versions.
For ASM on native targets, it is implemented as an alternate entrypoint
to memcpy which adds minimal code and overhead.
