RISC-V: Fix requirement handling on Zhinx+{D,Q}
This commit fixes how instructions are masked on Zhinx+Z{d,q}inx. fcvt.h.d and fcvt.d.h require ((D&&Zfh)||(Zdinx&&Zhinx)) and fcvt.h.q and fcvt.q.h require ((Q&&Zfh)||(Zqinx&&Zhinx)). bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Fix feature gate on INSN_CLASS_{D,Q}_AND_ZFH_INX. (riscv_multi_subset_supports_ext): Fix feature gate diagnostics on INSN_CLASS_{D,Q}_AND_ZFH_INX. gas/ChangeLog: * testsuite/gas/riscv/fp-zhinx-insns.d: Add Zqinx to -march for proper testing.
