Synopsis
 _m_pslld(__m64 a, __m64 count);
Description
Shift packed 32-bit integers in "a" left by "count" while shifting in zeros, and store the results in "dst".
Operation
FOR j := 0 to 1
	i := j*32
	IF count[63:0] > 31
		dst[i+31:i] := 0
	ELSE
		dst[i+31:i] := ZeroExtend32(a[i+31:i] << count[63:0])
	FI
