This is also doing the parse node split, allowing lower reliance in
formatter on the tokenized buffer (something that I may be touching more
due to import handling).
I was suggesting this because `FloatingPoint` is pretty long. `int` and
`float` should be familiar abbreviations. `unsigned` should be familiar
to developers too, but `UnsignedInt` still feels usefully clearer for
the additional chars.
