Teach beam_utils:replace_labels/4 to handle recv_{mark,set}
The missing support for renumbering labels in recv_mark
and recv_set did not seem to cause any problems, probably because
the insructions are introduced late and their labels would keep
their numbers. But it there will definitely be a problem if the
recv_mark and recv_set instructions would be introduced much earlier.
