Synopsis
 _mm256_maskz_mulhi_epu16(__mmask16 k, __m256i a, __m256i b);
Description
Multiply the packed unsigned 16-bit integers in "a" and "b", producing intermediate 32-bit integers, and store the high 16 bits of the intermediate integers 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]
		tmp[31:0] := a[i+15:i] * b[i+15:i]
		dst[i+15:i] := tmp[31:16]
	ELSE
		dst[i+15:i] := 0
	FI
ENDFOR
dst[MAX:256] := 0
