Synopsis
 _mm512_cmpord_pd_mask(__m512d a, __m512d b);
Description
Compare packed double-precision (64-bit) floating-point elements in "a" and "b" to see if neither is NaN, and store the results in mask vector "k".
Operation
FOR j := 0 to 7
	i := j*64
	k[j] := (a[i+63:i] != NaN AND b[i+63:i] != NaN) ? 1 : 0 
ENDFOR
k[MAX:8] := 0
