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

[Akira Hatanaka via Phabricator via cfe-commits]

I do have a plan to modify the auto upgrader to use the bundles when it's possible to do so, but I'm currently not considering landing the changes I reverted since they were only needed to avoid duplicating constant strings. I don't think we can avoid duplicating the string unless `objcarc::getRVMarkerModuleFlagStr()` can be moved to a file in `llvm/include/llvm/IR`.
