The formatting fix makes it harder to see what changes this PR is making to the test files. Also, for some reason `clang-format` is inserting spaces between `#` and `include`, which doesn't seem like an improvement.

I'll revert it back to https://github.com/llvm/llvm-project/pull/158664/commits/a642476464bd939f0516a8c1eed84f2cc268eafd and apply the formatting changes later if they are needed.
