Synopsis
 _mm256_maskz_adds_epi8(__mmask32 k, __m256i a, __m256i b);
Description
Add packed signed 8-bit integers in "a" and "b" using saturation, 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 31
	i := j*8
	IF k[j]
		dst[i+7:i] := Saturate8( a[i+7:i] + b[i+7:i] )
	ELSE
		dst[i+7:i] := 0
	FI
ENDFOR
dst[MAX:256] := 0
