[PATCH] D112941: [clang] Add support for the new pointer authentication builtins.

[Thorsten via Phabricator via cfe-commits]

tschuett added a comment.

If you look at the `immintrin.h` header, the access too many builtins is guarded by ifdefs.
` #if defined(__SSSE3__)`

The builtin `__builtin_ia32_reduce_smin_d512` is useless on aarch64.
