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

This is an alternative to https://reviews.llvm.org/D31735. Instead of deleting comdats that are invalidated, it keeps comdats valid by keeping their members in the same module and renaming the comdat if its leader is renamed. I think this is a cleaner solution.
