[PATCH] D31963: ThinLTOBitcodeWriter: keep comdats together, rename if leader is renamed

[Bob Haarman via Phabricator via llvm-commits]

inglorion updated this revision to Diff 94921.
inglorion added a comment.

Implemented more of @pcc's suggestions:

- Use Comdat* instead of StringRef in MergedMComdats.
- Populate MergedMComdats in existing loop instead of creating a new one.
- Remove regexes when matching unpromoted names.
