x86: correctly handle VMOVD with EVEX.W set outside of 64-bit mode
For the flavors having a GPR operand EVEX.W is ignored outside of 64-bit
mode. The mnemonic should therefore not be KMOVQ, the GPR operand should
not name a non-existing 64-bit register, just like is already the case
for the AVX counterparts, and the Disp8 scaling factor should be 4
rather than 8.
