objrange: Allow return of non-small ints.

jepler · jepler · commit 5afb3b736e9c · 2025-07-15T16:16:33.000+01:00
The magnitude of range() arguments is not restricted to "small"
ints, but includes "machine ints" which fit inside a register
but can only be represented as "long integer" objects in Python.
