A.5.35 CVTDQ2PD: Packed Signed INT32 to Packed Double-Precision FP
Conversion
CVTDQ2PD xmm1,xmm2/mem64 ; F3 0F E6 /r [WILLAMETTE,SSE2]
CVTDQ2PD converts two packed signed doublewords from the source operand
to two packed double-precision FP values in the destination operand.
The destination operand is an XMM register. The source can be either an
XMM register or a 64-bit memory location. If the source is a register,
the packed integers are in the low quadword.
