    * sched-deps.c (NON_FLUSH_JUMP_KIND, NON_FLUSH_JUMP_P): Define.
     (deps_analyze_insn): Mark JUMP_INSNs in
    last_pending_memory_flush that weren't added through
    flush_pending_lists with NON_FLUSH_JUMP_KIND.
    (sched_analyze_2, sched_analyze_insn): Check NON_FLUSH_JUMP_P
    on INSN_LIST instead of JUMP_P check on its operand.
    * sched-rgn.c (concat_INSN_LIST): Copy over REG_NOTE_KIND.
