pl/math: Reduce order of single-precision tan polynomial For both vector and scalar routines we reduce the order from 6 to 5. For vector routines, this requires reducing RangeVal as for large values the tan polynomial is not quite accurate enough. However the cotan polynomial is used in the inaccurate region in the scalar routine, so this does not need to change. Accuracy of scalar routine is unchanged. Accuracy in both vector routines is now 3.45 ULP, with the same worst-case.
