Bulk formatting of Clang is still under discussion in https://discourse.llvm.org/t/rfc-clang-format-all-the-things/76614. At least I don't see a consensus called there one way or another.

Our [developer policy](https://llvm.org/docs/DeveloperPolicy.html) states the following:

So yeah, we can't merge this at the moment, unfortunately. This might change in the future, though, as more people lean towards bulk formatting after several years of very slow gradual reformatting with accordance to our current policy.
