=for apidoc Am|REGEXP *|SvRX|SV *sv

Convenience macro to get the REGEXP from a SV.  This is approximately
equivalent to the following snippet:

if (SvMAGICAL(sv))
        mg_get(sv);
    if (SvROK(sv))
        sv = MUTABLE_SV(SvRV(sv));
    if (SvTYPE(sv) == SVt_REGEXP)
        return (REGEXP*) sv;

C<NULL> will be returned if a REGEXP* is not found.

=for apidoc Am|bool|SvRXOK|SV* sv

Returns a boolean indicating whether the SV (or the one it references)
is a REGEXP.

If you want to do something with the REGEXP* later use SvRX instead
and check for NULL.

 * immediately follow; finally the used RXf-only (unshared) bits, so that the
 * highest bit in the word is used.  This gathers all the unused bits as a pool
 * in the middle, like so: 11111111111111110000001111111111
 * where the '1's represent used bits, and the '0's unused.  This design allows

 * off the other end if we need a non-shared bit, without disturbing the other
 * bits.  This maximizes the likelihood of being able to change things without
 * breaking binary compatibility.
 *
 * To add shared bits, do so in op_reg_common.h.  This should change
 * _RXf_PMf_SHIFT_NEXT so that things won't compile.  Then come to regexp.h and
 * op.h and adjust the constant adders in the definitions of RXf_BASE_SHIFT and
 * Pmf_BASE_SHIFT down by the number of shared bits you added.  That's it.
 * Things should be binary compatible.  But if either of these gets to having
 * to subtract rather than add, leave at 0 and instead adjust all the entries
 * that are in terms of it.  But if the first one of those is already
 * RXf_BASE_SHIFT+0, there are no bits left, and a redesign is in order.
 *
 * To remove unshared bits, just delete its entry.  If you're where breaking
 * binary compatibility is ok to do, you might want to adjust things to move
 * the newly opened space so that it gets absorbed into the common pool.
 *
 * To add unshared bits, first use up any gaps in the middle.  Otherwise,
 * allocate off the low end until you get to RXf_BASE_SHIFT+0.  If that isn't
 * enough, move RXf_BASE_SHIFT down (if possible) and add the new bit at the
 * other end instead; this preserves binary compatibility.
 *
 * For the regexp bits, PL_reg_extflags_name[] in regnodes.h has a comment
