    * basic-block.h (pre_and_rev_post_order_compute_fn): New function.
    * cfganal.c (pre_and_rev_post_order_compute_fn): New function
    as worker for ...
    (pre_and_rev_post_order_compute): ... which now wraps it.
    * graph.c (draw_cfg_nodes_no_loops): Use
    pre_and_rev_post_order_compute_fn to avoid ICEing and dependence
    on cfun.
