This patch revises the algorithm for computing the error function.
It uses the approximation method by Abramowitz and Stegun.
The new method chooses the fast path if the argument is less than 2.5.
The fast path utilizes the Estrin method for fast evaluation of the polynomials, and does not require computing the exponential function.
