[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]

ahatanak updated this revision to Diff 322867.
ahatanak added a comment.

Fix two bugs which were discovered.

- Fix bug in `replaceUsesOfNonProtoConstant`.
- Teach SCCP not to replace the return of a "clang.arc.rv" call with a constant.
