objint_mpz: Quick&dirty implementation of bitwise operations.
...
Made solely to unbreak int-long.py test which in turn uncovered thinko
with implementation of inplace ops. On mpz level, bitwise ops implemented
only for same-sign numbers, and are not efficient (unconditional calling of
mpn_cmp() is apparently superfluous).

py: Implement integer overflow checking for * and << ops.
...
If operation will overflow, a multi-precision integer is created.

py: Implement bit-shift and not operations for mpz.
...
Implement not, shl and shr in mpz library. Add function to create mpzs
on the stack, used for memory efficiency when rhs is a small int.
Factor out code to parse base-prefix of number into a dedicated function.

Add arbitrary precision integer support.
...
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).
