Optimize `rb_must_asciicompat`
While profiling `strscan`, I noticed `rb_must_asciicompat` was quite
slow, as more than 5% of the benchmark was spent in it: https://share.firefox.dev/49bOcTn
By checking for the common 3 ASCII compatible encoding index first,
we can skip a lot of expensive operations in the happy path.
