Thank you for you work!

Please add a release note in `clang-tools-extra/docs/ReleaseNotes.rst`.

Please read <https://llvm.org/docs/CodingStandards.html> and follow requirements/suggestions in this document such as preferring `llvm::SmallVector` and not using braces on simple single-statement bodies of `if` statements.
