2e2e15cec2 py/mpz: Complete implementation of mpz_{and,or,xor} for negative args.
For these 3 bitwise operations there are now fast functions for
positive-only arguments, and general functions for arbitrary sign
arguments (the fast functions are the existing implementation).

By default the fast functions are not used (to save space) and instead
the general functions are used for all operations.

Enable MICROPY_OPT_MPZ_BITWISE to use the fast functions for positive
arguments.

22b2265053 py/parse: Improve constant folding to operate on small and big ints.
Constant folding in the parser can now operate on big ints, whatever
their representation.  This is now possible because the parser can create
parse nodes holding arbitrary objects.  For the case of small ints the
folding is still efficient in RAM because the folded small int is stored
inplace in the parse node.

Adds 48 bytes to code size on Thumb2 architecture.  Helps reduce heap
usage because more constants can be computed at compile time, leading to
a smaller parse tree, and most importantly means that the constants don't
have to be computed at runtime (perhaps more than once).  Parser will now
be a little slower when folding due to calls to runtime to do the
arithmetic.

c9fa667252 tests: Add tests for non-compliant behaviour.
These tests are intended to improve coverage and provide a record of
behaviour that's either not implemented or non-compliant to CPython.
