[PATCH] D139163: Utils: Add utility pass to lower ifuncs

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

You previously said "OpenCL forbids function pointers. If you use target_clones in clang, there's no function pointer in the source and the compiler takes care of everything. I want to patch up subtarget specific implementations of builtin functions. It's not for end users"

I take it that if `target_clones` supports non-ifunc use, this patch is not needed. It seems that  `target_clones` indeed works without ifunc (inefficient now, but can be improved), so may I assume that this is not needed?
