  Log Message:
  -----------
  OP_REF_CMP - don't apply to a TARGMY reftype

OP_REF_CMP does not currently support the TARGMY optimization, so should
not replace an OP that has already had it applied.

GH#24630 provided an example of this happening, along the lines of:

    my $bool = ( ($r = reftype($x)) eq 'HASH' or $r eq 'ARRAY' );

Where the assignment into `$r` is via TARGMY on the `reftype`.
