Replaced set_irn_n(*, -1, *) and get_irn_n(*, -1) by new get_nodes_block()/set_nodes_block() implementation caveats: - the old outs do not see the anchor node yet - the new edges wrongly use get_irn_n(*, -1) - the new edges do not realize that the move of a node moves all its Projs - the anchor node still must have the -1 input set (due to edges bug...)
