[PATCH] D21185: [clang-tidy] Add performance-emplace-into-containers

[Vedant Kumar via cfe-commits]

vsk added a reviewer: flx.
vsk updated this revision to Diff 60194.
vsk added a comment.

- Fix handling of push_back(X(/* comment */)).
- Don't try to emit a warning when the callee comes from a macro expansion.
- Get rid of a weird/wrong comment about checking for "default constructors".

As a side note, I'd appreciate advice on how to apply this check to the llvm codebase (via some kind of cmake invocation?) and gather numbers.
