[PATCH] D92808: [ObjC][ARC] Use operand bundle 'clang.arc.rv' instead of explicitly emitting retainRV or claimRV calls in the IR

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Another thing I noticed that there's verifier support missing. I think we should at least check that only a single `clang.arc.rv` bundle is specified (https://github.com/llvm/llvm-project/blob/main/llvm/lib/IR/Verifier.cpp#L3191). We should probably also enforce that the bundle is only provided for functions with an `i8*` return type. That can also be done after the main patch lands.
