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`
