vcvtdq2pd was incorrectly declared to take 3 operands, the use of the
macro Cvtdq2pd meant that the call was vcvtdq2pd(dst, dst, src). This
is an incorrect encoding. Our tests happen to pass because dst was xmm0,
which made it accidentally correct.

This fixes it by moving cvtdq2pd out of the macro list.
