Should I put the braces back and add handling of do-while for `RemoveBracesLLVM`?

Good idea. I don't think there's any consensus specifically about this but will ask on discourse.llvm.org. To err on the conservative side, I will manually add the braces back for now.

I will leave it as is and use it as a test case for later. Implementing this would add more complexity to `RemoveBracesLLVM`, which is complex enough already. I will look into it in a few months as I will be away for the summer.
