eliminate RF_utf8 flag from PL_reg_flags

This global flag indicates whether the currently executing regex is utf8.
Replace it with a boolean var local to to the matching function, and pass
it around via function args, or as a member of the regmatch_info struct.

This is a first step to eliminating PL_reg_flags.
