Synopsis
 _mm512_mask_cmpnlt_pd_mask(__mmask8 k1, __m512d a, __m512d b);
Description
Compare packed double-precision (64-bit) floating-point elements in "a" and "b" for not-less-than, 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*64
	IF k1[j]
		k[j] := (!(a[i+63:i] < b[i+63:i])) ? 1 : 0
	ELSE 
		k[j] := 0
	FI
ENDFOR
k[MAX:8] := 0
