Format the two RecursiveASTVisitors

Apply current ToT clang-format on the two RAVs to reduce delta and help
identify differences between the two.

We lose a little pretty formatting in the headers but that's the price to pay
so we can diff these two files effectively and look to a future where we don't
have to maintain two copies of this code.

Formatting and whitespace only.
