        * gcse.c (gcse_main): Do not call free_bb_mem anymore.
        * toplev.c (rest_of_compilation): Likewise.
        * haifa-sched.c (build_control_flow): Use flow generated edge
        list to build the haifa specific edge list.
        (find_rgns): Use new CFG data structures instead of pred/succ lists.
        (schedule_insns): Do not build pred/succ lists anymore.  Instead
