[PATCH] D97824: [ObjC][ARC] Don't add operand bundle `clang.arc.attachedcall` to a call if the call already has the operand bundle

[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak added a comment.

We could emit a call to `@llvm.objc.retain` instead of the call to `@llvm.objc.retainAutoreleasedReturnValue`, but this doesn't seem to happen often and ARC optimizer can remove or replace the call anyway, so I'm just letting the front-end emit `@llvm.objc.retainAutoreleasedReturnValue` for simplicity.
