	* tree-ssa-ccp.c (fold_stmt): Don't optimize OBJ_TYPE_REFs if that
	would result in an already finalized unreachable node becoming
	reachable while cgraph_global_info_ready.
	
	* class.c: Include cgraph.h.
	(cp_fold_obj_type_ref): Set node->local.vtable_method.
	* Make-lang.in (cgraph.o): Depend on $(CGRAPH_H).
