re_op_compile(): rename pm_flags to rx_flags

The orig_pm_flags argument and its modified copy, pm_flags, actually
contain bits related to REGEXPs (i.e. RXf_*) rather than PMOPs
(i.e.  PMf_*); although there is some overlap between the two sets of
bit flags.

Rename the variables to make this less unclear.
Ditto for re_compile().
