Synopsis
 _mm256_mask_subs_epi16(__m256i src, __mmask16 k, __m256i a, __m256i b);
Description
Subtract packed signed 16-bit integers in "b" from packed 16-bit integers in "a" 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 15
	i := j*16
	IF k[j]
		dst[i+15:i] := Saturate16(a[i+15:i] - b[i+15:i])
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI	
ENDFOR
dst[MAX:256] := 0
