Claire Xenia Wolf 2652cfad8d RISC-V: Support riscv bitmanip frozen ZBA/ZBB/ZBC instructions (v0.93). 
In fact rev8/orc.b/zext.h are the aliases of grevi/gorci/pack[w], so we
should update them to INSN_ALIAS when we have supported their true instruction
in the future.  Though we still use the [MATCH|MAKS]_[GREVI|GORCI|PACK|PACKW]
to encode them.  Besides, the orc.b has the same encoding both in rv32 and
rv64, so we just keep one of them in the opcode table.

This patch is implemented according to the following link,
