Thanks for the suggestions! After taking a look, `.clang-format-ignore` isn't used in current repo while `// clang-format off:<reason>` is used (e.g. at 7 different places in this [file](https://github.com/llvm/llvm-project/blob/450462cbaceddf57812ce15b5135b17f65a77654/clang/lib/Analysis/UnsafeBufferUsage.cpp)). I could make possibly add a few `// clang-format off` and `// clang-format on` around c++ macros in an nfc pull request.

Meanwhile, I'll send out a follow up change to update https://llvm.org/docs/InstrProfileFormat.html
