Add a new function annotation __no_profile that expands to

CC_HAS_NO_PROFILE_FN_ATTR and ARCH_WANTS_NO_INSTR. Make GCOV and PGO
depend on either !ARCH_WANTS_NO_INSTR or CC_HAS_NO_PROFILE_FN_ATTR.

Awesome; thanks everyone! I'm doing a Clang rebuild now, and will do
kernel testing and push this to my for-next/clang/features tree shortly.
