I don't have issues with reformatting the entire files, and https://www.llvm.org/docs/Contributing.html says nothing about that.

But I guess convention is to reformat only parts you are going to change - less noise in blame output, and less conflict resolution for others who have pending PRs here.

On a positive side, if landed, less friction for future editors.
