        Patch to allow moving conditional jumps through some instructions.

        * sel-sched.c (moveup_rhs): Allow jumps to go through instructions
        if dependencies allow.
        (sel_rank_for_schedule): Prioritize jumps over other instructions.
        (fill_vec_av_set): Added more debug.
        (generate_bookkeeping_insn): Reset sched times on
        bookkeeping instructions.
        (move_cond_jump): New function.
        (fill_insns): Now handles scheduling of jumps.
        (sel_region_init): Added check to stop scheduling empty regions early.
        (sel_region_finish): Added some dump.
        (sel_sched_region_1): Cleanup.
        (sel_sched_region): Same.

        * sel-sched-ir.c (sel_split_edge): Remove now wrong assert.
        (bookkeeping_can_be_created_if_moved_through_p): Remove wrong
        early check.
