Synopsis
 _mm_maskz_cvtepu8_epi32(__mmask8 k, __m128i a);
Description
Zero extend packed unsigned 8-bit integers in th elow 4 bytes of "a" to packed 32-bit integers, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
	i := 32*j
	l := 8*j
	IF k[j]
		dst[i+31:i] := ZeroExtend32(a[l+7:l])
	ELSE
		dst[i+31:i] := 0
	FI
ENDFOR
dst[MAX:128] := 0
