Nicholas Nethercote df56c50cee Make TokenType::from_u32 foolproof.
Currently it relies on having the right integer for every variant, and
if you add a variant you need to adjust the integers for all subsequent
variants, which is a pain.

This commit introduces a match guard formulation that takes advantage of
the enum-to-integer conversion to avoid specifying the integer for each
variant. And it does this via a macro to avoid lots of boilerplate.
