Synopsis
 _mm512_cmpunord_ps_mask(__m512 a, __m512 b);
Description
Compare packed single-precision (32-bit) floating-point elements in "a" and "b" to see if either is NaN, and store the results in mask vector "k".
Operation
FOR j := 0 to 15
	i := j*32
	k[j] := ((a[i+31:i] == NaN) OR (b[i+31:i] == NaN)) ? 1 : 0
ENDFOR
k[MAX:16] := 0
