Refactor `byte_search!` macro to move logic out of the main loop. This ensures the compiler unrolls the loop.
This speeds up lexing single-line comments by 20%-25% on the benchmarks which contain enough comments for the change to register. Presumably the loop wasn't unrolled previously.
The code required to do this is a little odd. It adds an extra `loop {}` which always exits on the first turn (so not really a useful loop), but is required to be able to use `break` to exit that "loop", making 2 different paths for (1) matching byte found and (2) `for` loop completed without finding any match.
This is only way I could find to produce this behavior without using a macro. Is there a more "normal" way to get the same logic?
