[issue8748] integer-to-complex comparisons give incorrect results

2.7 patch attached.  The implementation is mostly the same as the 3.2 one, but there is one quirk.  Namely, 2.7 (and other 2.x's) has the following odd behavior:

   >>> 1j < None
   False
   >>> 1j < 1
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   TypeError: no ordering relation is defined for complex numbers

To perserve this behavior I had to do the type checks for 'int', 'long', 'complex', and 'float' at the beginning.  I tried 'PyNumber_Check' first, but it returns 1 for old-style classes since the number protocol is filled in for the 'instance' type.
