regcomp.h: Allow compiler to perform calculation

Instead of doing the calculation of how many bytes a 256 bitmap
occupies, let the compiler do it.  I believe we are not too far away
from having the ability to allow applications to recompile Perl to
increase the bitmap size trading speed for memory.  ICU has an 8192
bitmap last time I checked.
