I guess it's a good idea to try to fold constants as we build them... it's slightly more efficient, and it could avoid spurious "overdefined" markings in some cases.  Might as well make a pass over the whole file while you're at it to find other places where we do something similar.

That said, I doubt it makes much of a difference in practice.
