Synopsis
 _mm256_mask_compress_ps(__m256 src, __mmask8 k, __m256 a);
Description
Contiguously store the active single-precision (32-bit) floating-point elements in "a" (those with their respective bit set in writemask "k") to "dst", and pass through the remaining elements from "src".
Operation
size := 32
m := 0
FOR j := 0 to 7
	i := j*32
	IF k[j]
		dst[m+size-1:m] := a[i+31:i]
		m := m + size
	FI
ENDFOR
dst[255:m] := src[255:m]
dst[MAX:256] := 0
