Simplify lexer transition code.
This removes an if-check from the top of get_transition, removes an if-
check from the top of Lexer::next(), simplifies a bounds check, and
removes bitfields from the index array. Disappointingly, on my machine,
I can't measure any change at all; `get_transition` and `next`
stubbornly remain at about 4-5% of total nanobench time for
`sksl_large`. However, it's still simpler and hopefully slightly smaller
code.
