Synopsis
 _mm512_mask_conflict_epi64(__m512i src, __mmask8 k, __m512i a);
Description
Test each 64-bit element of "a" for equality with all other elements in "a" closer to the least significant bit using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). Each element's comparison forms a zero extended bit vector in "dst".
Operation
FOR j := 0 to 7
	i := j*64
	IF k[j]
		FOR l := 0 to j-1
			m := l*64
			dst[i+l] := (a[i+63:i] == a[m+63:m]) ? 1 : 0
		ENDFOR
		dst[i+63:i+j] := 0
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:512] := 0
