x86: Properly encode vmovd with 64-bit memeory

For historical reason, we allow movd/vmovd with 64-bit register and
memeory operands.  But for vmovd, we failed to handle 64-bit memeory
operand.  This has been gone unnoticed since AT&T syntax always treats
memory operand as 32-bit memory.  This patch properly encodes vmovd
with 64-bit memeory operands.  It also removes AVX512 vmovd with 64-bit
operands since GCC has

    case TYPE_SSEMOV:
      switch (get_attr_mode (insn))
        {
        case MODE_DI:
          /* Handle broken assemblers that require movd instead of movq.  */
          if (!HAVE_AS_IX86_INTERUNIT_MOVQ
              && (GENERAL_REG_P (operands[0]) || GENERAL_REG_P (operands[1])))
            return "%vmovd\t{%1, %0|%0, %1}";
          return "%vmovq\t{%1, %0|%0, %1}";

and all AVX512 GNU assemblers set HAVE_AS_IX86_INTERUNIT_MOVQ, GCC won't
generate AVX512 vmovd with 64-bit operand.
