As a Joint Venture between AMD and Haiguang Information Technology Co., Ltd.,
Hygon aims to provide x86 server processor in China market. The first
generation processor Dhyana (family 18h) shares similar architecture with
AMD family 17h.

As Dhyana support in QEMU already have been merged in qemu-4.1.0 [1], to add
Dhyana support in libvirt, we have added a new Dhyana CPU model file
x86_Dhyana.xml in cpu_map directory, and also we have added a series of
Dhyana test files.

We have tested the patches on Hygon Dhyana machine with the result that it
has successfully worked as expected.

Thanks for your contribution & apologies for the delay in reviewing
it. I've squashed patch 4 into patch 2 and merged this.
