    gdb/djgpp: Add Hygon Dhyana processor support
    
    Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture between
    AMD and Haiguang Information Technology Co.,Ltd., which aims at
    providing high performance x86 processors for the China server market.
    Its first generation processor codename is Dhyana, which originates
    from AMD technology and shares most of the architecture with AMD's
    family 17h, but with different CPU Vendor ID("HygonGenuine")/Family
    series number(Family 18h).
