CharClass::Matcher switches on chars, but can easily be optimized to switch on shorts or ints,
max U32, endian specific. (via #ifdef in the generated .h)
See the "-switch and fast memcmp" section at http://blogs.perl.org/users/rurban/2014/08/perfect-hashes-and-faster-than-memcmp.html

This generates code for regcharclass.h
