PR optimization/13024
* toplev.c (rest_of_handle_new_regalloc): Remove rebuild_notes
parameter.
(rest_of_handle_old_regalloc): Likewise.  Add rebuild_notes
declaration.  Rebuild jump labels following local_alloc if necessary.
(rest_of_compilation): Remove rebuild_label_notes_after_reload
declaration.  Don't pass rebuild_notes parameter to
rest_of_handle_new_regalloc and rest_of_handle_old_regalloc.
Don't rebuild jump labels.
