Synopsis
 _mm_mask_cmpeq_epu16_mask(__mmask8 k1, __m128i a, __m128i b);
Description
Compare packed unsigned 16-bit integers in "a" and "b" for equality, and store the results in mask vector "k" using zeromask "k1" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
	i := j*16
	IF k1[j]
		k[j] := ( a[i+15:i] == b[i+15:i] ) ? 1 : 0
	ELSE 
		k[j] := 0
	FI
ENDFOR
k[MAX:8] := 0
