If use OverflowError as a sign of infinite iterator in __length_hint__, this should be documented as a legitimate use case for OverflowError.

itertools.repeat.__length_hint__() and reversed.__length_hint__() currently raise a TypeError for infinite iterator. reversed.__length_hint__() returns NotImplemented (which raises a TypeError when convert to a C integer). Both TypeError and NotImplemented are handled by the consumer of __length_hint__: in PyObject_LengthHint(). An OverflowError is treated as error.
