RISC-V: Support -mcpu for XiangShan Kunminghu cpu.
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.

* config/riscv/riscv-cores.def (RISCV_TUNE): New cpu tune.
(RISCV_CORE): New cpu.
* doc/invoke.texi: Ditto.
