This patch adds support for the XiangShan Kunminghu CPU in GCC, allowing
the use of the `-mcpu=xiangshan-kunminghu` option.
XiangShan-KunMingHu is the third-generation open-source high-performance
RISC-V processor.[1] You can find the corresponding ISA extension
from the
XiangShan Github repository.[2] The latest news of KunMingHu can be
found
in the XiangShan Biweekly.[3]

A dedicated scheduling model for KunMingHu's hybrid pipeline will be
proposed in a subsequent PR.

After fixing the typo (extraneous underscore) pointed out by Xi this
is fine for the trunk.
