Sorry I misread your original comment.

These functions exist so that we can guarantee that these particular instructions will be emitted; the other option was LLVM IR intrinsics and Clang builtins, this was the other patch (https://reviews.llvm.org/D66479).

We are planning on abandoning that patch in favour of this one after the discussions on the patch and the mailing list.
