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.
