This seems reasonable to me, but either Per or Andrew will have to
approve.  Perhaps a comment explaining why we're doing this would be
helpful.

Just to clarify, we only collect more if later passes determine that
code in the block is dead.  Currently in this situation, the dead
trees will linger since we still have a pointer to them.
