8253081: G1 fails on stale objects in archived module graph in Open Archive regions

Change the handling of Open Archive areas, instead of assuming that everything in there is live always, a root containing references to all live root objects is provided. Adapt G1 to handle Open Archive regions as any other old region apart from never compacting or evacuating them.
