Synopsis
 _mm256_mask_adds_epu8(__m256i src, __mmask32 k, __m256i a, __m256i b);
Description
Add packed unsigned 8-bit integers in "a" and "b" using saturation, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
	i := j*8
	IF k[j]
		dst[i+7:i] := SaturateU8( a[i+7:i] + b[i+7:i] )
	ELSE
		dst[i+7:i] := src[i+7:i]
	FI
ENDFOR
dst[MAX:256] := 0
