Synopsis
 _mm256_mask_expandloadu_epi32(__m256i src, __mmask8 k, void const* mem_addr);
Description
Load contiguous active 32-bit integers from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 7
	i := j*32
	IF k[j]
		dst[i+31:i] := MEM[mem_addr+m+31:mem_addr+m]
		m := m + 32
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:256] := 0
