     * Test whether obj was finalized before prop's last dereference.
     *
     * This can happen when a deleted property is held by a property iterator
     * object (which points to obj, keeping obj alive so long as the property
     * iterator is reachable).  As soon as the GC finds the iterator to be
     * unreachable, it will finalize the iterator, and may also finalize obj,
     * in an unpredictable order.  If obj is finalized first, its map will be
     * null below, and we need only free prop.
     *
     * In the more typical case of a property whose last reference (from a
     * symbol in obj's scope) goes away before obj is finalized, we must be
     * sure to free prop's slot and unlink it from obj's property list.
