Yes.  I think it will be easier to change the lesser-used
make-record-constructor-descriptor procedure than the record-constructor
descriptor if we decide to do so down the road.

But in keeping with the use of #f to signify a default
constructor-descriptor in other contexts, I think we should use that
convention for record-constructor as well, so record-constructor takes two
arguments:  rtd and record-constructor, where record-constructor may be
#f.  I'll go ahead and make this change unless I hear an objection.
