* flow.c (flow_delete_insn): If we delete a CODE_LABEL, also remove
it from the nonlocal_goto_handler_labels list.
* jump.c (delete_insn): Likewise.
(jump_optimize_1): Also recompute LABEL_NUSES when we are just
marking labels.
* rtl.h (remove_node_from_expr_list): Declare.
* rtlanal.c (remove_node_from_expr_list): New function.
