During a shared GC we need to iterate the twice: for marking and later when updating pointers after evacuation. This CL introduces a new remembered set to avoid the second heap iteration, the remembered set is created when iterating the client heaps for marking. When updating pointers, the GC only needs to visit slots in the remembered set. CLIENT_TO_SHARED is only used during GC atm.
