Synopsis
 _mm512_maskz_xor_epi64(__mmask8 k, __m512i a, __m512i b);
Description
Compute the bitwise XOR of packed 64-bit integers 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 7
	i := j*64
	IF k[j]
		dst[i+63:i] := a[i+63:i] XOR b[i+63:i]
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
