regcomp.h: Make some #defines sequential

ANYOF_MAX is used as the upper boundary in loops.  If we keep it larger
than necessary, the loop does extraneous iterations.

The #defines that come after ANYOF_MAX are moved down to start with it.
This is useful in a later commit that will create an entry in
l1_char_class_tab.h for vertical white space determination.
