[PATCH] D23651: [clang-rename] improve performance for rename-all

[Kirill Bobyrev via cfe-commits]

omtcyfz added a comment.

Actually, it might make sense to merge `rename-at` and `rename-all` after all. Passing a list of `old-name`/`offset` -> `new-name` is just easier.

But that's for another patch.
