I just found a major bug in SelectionDAG.  Well, I found it several weeks ago
and finally diagnosed it today.

One possible fix comes down to holding SDUses about to be processed in
a queue.  But this would require the SDUse copy constructor to be public.

Why is it private and unimplemented right now?  What's the assumption
that's trying to protect?
