[PATCH] D114425: [clang] Add __builtin_bswap128

[David Majnemer via Phabricator via cfe-commits]

OOC, how hard would it be to generalize this builtin a little? It is nice that we have builtins like `__builtin_add_overflow` which do the right thing regardless of their input.

It seems like it would be nice if we started to expose more intrinsics which did the right thing regardless of operand width; another bonus is that it composes well with language features like `_BitInt`.
