Synopsis
 _mm256_maskz_mul_pd(__mmask8 k, __m256d a, __m256d b);
Description
Multiply packed double-precision (64-bit) floating-point elements in "a" and "b", 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 3
	i := j*64
	IF k[j]
		dst[i+63:i] := a[i+63:i] * b[i+63:i]
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:256] := 0
