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).
