    i386: Fix up last -masm=intel operand of vcvthf82ph [PR124349]

    gas expects for this instruction
    vcvthf82ph      xmm30, QWORD PTR [r9]
    vcvthf82ph      ymm30, XMMWORD PTR [r9]
    vcvthf82ph      zmm30, YMMWORD PTR [r9]
    i.e. the memory size is half of the dest register size.
    We currently emit it for the last 2 forms but emit XMMWORD PTR
    for the first one too.  So, we need %q1 for V8HF and for V16HF/V32HF
    can either use just %1 or %x1/%t1.  There is no define_mode_attr
    that would provide those, so I've added one just for this insn.
