Ack, our patches are fighting.

Yours will now be quadratic at weak_finish time.  We really ought to be
using hash tables for these things, but for now we can get by.

I'm not sure whether your patch or mine is better, but I think I prefer
mind on the grounds that it eliminates the references to the wrong DECLs
sooner.  DECLs take up lots of space, and we want to return them to the
collector.

Thoughts?
