NOTE: Clang-Format Team Automated Review Comment

It looks like your clang-format review does not contain any unit tests, please try to ensure all code changes have a unit test (unless this is an `NFC` or refactoring, adding documentation etc..)

Add your unit tests in `clang/unittests/Format` and you can build with `ninja FormatTests`.  We recommend using the `verifyFormat(xxx)` format of unit tests rather than `EXPECT_EQ` as this will ensure you change is tolerant to random whitespace changes (see FormatTest.cpp as an example)

For situations where your change is altering the TokenAnnotator.cpp which can happen if you are trying to improve the annotation phase to ensure we are correctly identifying the type of a token, please add a token annotator test in `TokenAnnotatorTest.cpp`


After https://reviews.llvm.org/D151954 we've noticed some issues w/
clang-format behavior, as outlined in
https://github.com/llvm/llvm-project/issues/63170.

Valid C/C++ files, that were previously accepted, are now rejected by
clang-format, emitting the message:

"The new replacement overlaps with an existing replacement."

This test will fail, despite being a valid(if trivial) cpp file.
