Here is one more, final attempt to improve fast summation, somewhat.

This version inspects the type of both the sum and the first item and 
adds all ints and floats without any PyNumber_Add() call and in order.

Also, the results for this test case are compatible:

>>> d = [1000000000000000, -1000000000000000.0, .0000000000000001, 
.0000000000000001]
>>> sum(d)
2e-16
>>> d[0] + sum(d[1:])
0.0
