    I tried to use generic structure and macro, but many members of generic
    struct insn are not used for MPX, and except this I have to add one
    member into this structure. So I define mpx specific struct insn.

    And so I guess only struct insn_field and several macros like X86_XXX
    may use generic version. Anyway, I will try to use their generic version
    in next version for this patchset.

    Thanks,
    Qiaowei
