<pre>
    After https://reviews.llvm.org/D151954 we're seeing some significant regressions in the output of clang-format.
[formating_output.zip](https://github.com/llvm/llvm-project/files/11680534/formating_output.zip)

The code in this example is generated and formatted w/ clang-format and diffed against a golden file (golden.h). To be clear the golden and generated file are both formatted w/ clang-format prior to diffing to avoid needlessly detecting irrelevant changes. Our `.clang-format` file can be found here: https://cs.opensource.google/fuchsia/fuchsia/+/main:.clang-format

As can be seen in bad.h, includes are indented when they shouldn't be and there is whitespace added after lines in many cases. There are also a number of empty lines left in the file.

To illustrate I'm incuding a snippet of the first 30 lines from `golden.h` and `bad.h`: 

`golden.h`
