RISC-V: Add instructions and operand set for z[fdq]inx
Reuse float instructions in INSN_CLASS_F/D/Q, use riscv_subset_supports to
verify if z*inx enabled and use gpr instead of fpr when z*inx is enable.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Added support for
z*inx extension.
gas/ChangeLog:
* config/tc-riscv.c (riscv_ip): Added register choice for z*inx.
include/ChangeLog:
* opcode/riscv.h (enum riscv_insn_class): Reused INSN_CLASS_* for z*inx.
opcodes/ChangeLog:
* riscv-dis.c (riscv_disassemble_insn): Added disassemble check for
z*inx.
* riscv-opc.c: Reused INSN_CLASS_* for z*inx.
