Synopsis
 _mm256_maskz_sub_epi16(__mmask16 k, __m256i a, __m256i b);
Description
Subtract packed 16-bit integers in "b" from packed 16-bit integers in "a", 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 15
	i := j*16
	IF k[j]
		dst[i+15:i] := a[i+15:i] - b[i+15:i]
	ELSE
		dst[i+15:i] := 0
	FI	
ENDFOR
dst[MAX:256] := 0
