gc: bugfix: maintain tail pointer in new sweep code.
* gc.c (sweep): The new logic for removing a deleted
heap's blocks from the free list must correctly maintain
free_tail. Whenever a node is deleted which is the tail node,
the tail pointer must move to the parent's tail field, or to
the free_list pointer. We don't need to do anything afterward
for the free_list == 0 case; that is taken care of.
