pack-objects: equal objects in size should delta against newer objects
Before finding best delta combinations, we sort objects by name hash, then by size, then by their position in memory. Then we walk the list backwards to test delta candidates. We hope that a bigger size usually means a newer objects. But a bigger address in memory does not mean a newer object. So the last comparison must be reversed.
