Improve integer arithmetic fast paths for exact ``int`` values that fit
in the signed 64-bit range but are not compact Python integers.
Speed up addition, subtraction, and multiplication of large integers
(those too big for CPython's inline "compact" representation).
Also fixes a crash when using such integers as list indices in
specialized code paths.
