The only existing test that fails is range(1e100, 1e101, 1e101) 
producing a TypeError. It will now produce

>>> range(1e100, 1e101, 1e101)
__main__:1: DeprecationWarning: integer argument expected, got float
[10000000000000000159028911097599180468360808563945281389781327557747838
772170381060813469985856815104L]

Note that range(1e100, 1e101) would still fail:
>>> range(1e100, 1e101)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: range() result has too many items

An alternative solution would be to disallow non-ints regardless of 
their value, but that is more likely to break someone's code.
