RISC-V: Add zhinx extension supports.
The zhinx extension is a sub-extension in zfinx, corresponding to
zfh extension but use GPRs instead of FPRs.
This patch expanded the zfh insn class define, since zfh and zhinx
use the same opcodes, thanks for Nelson's works.
changelog in V2: Add missing classes of 'zfh' and 'zhinx' in
"riscv_multi_subset_supports_ext".

* elfxx-riscv.c (riscv_multi_subset_supports): New extensions.
(riscv_multi_subset_supports_ext): New extensions.
