Synopsis
 _mm_atan2_ph(__m128h a, __m128h b);
Description
Compute the inverse tangent of packed half-precision (16-bit) floating-point elements in "a" divided by packed elements in "b", and store the results in "dst" expressed in radians.
Operation
FOR j := 0 to 7
	i := j*16
	dst[i+15:i] := ATAN2(a[i+15:i], b[i+15:i])
ENDFOR
dst[MAX:128] := 0
