Uh oh!

The long_from_string_base() might return a small integer, when the _pylong.py is used to do conversion. Hence, we must be careful here to not smash it "small int" bit by using the _PyLong_FlipSign().
(cherry picked from commit db5936c)

@skirpichev: I backported manually the change to 3.13. I reimplemented _PyLong_IsSmallInt() for 3.13.
