Synopsis
 _mm256_mask_max_epu16(__m256i src, __mmask16 k, __m256i a, __m256i b);
Description
Compare packed unsigned 16-bit integers in "a" and "b", and store packed maximum values 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] := MAX(a[i+15:i], b[i+15:i])
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:256] := 0
