gh-60203: Revert changes in cycle.__setstate__ (#99982)
In case if only True/False be supported as boolean arguments in future,
we should continue to support 1/0 here.

bpo-15999: Accept arbitrary values for boolean parameters. (#15609)
builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

bpo-43413: Fix handling keyword arguments in subclasses of some buitin classes (GH-26456)
* Constructors of subclasses of some buitin classes (e.g. tuple, list,
  frozenset) no longer accept arbitrary keyword arguments.
* Subclass of set can now define a __new__() method with additional
  keyword parameters without overriding also __init__().

bpo-42536: GC track recycled tuples (GH-23623)
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip

Previously, they could have become untracked by a prior garbage collection.

Mark some individual tests to skip when --pgo is used.  The tests

T. Wouters 5466d4af5f bpo-29942: Fix the use of recursion in itertools.chain.from_iterable. (#889)
Fix the use of recursion in itertools.chain.from_iterable. Using recursion
is unnecessary, and can easily cause stack overflows, especially when
building in low optimization modes or with Py_DEBUG enabled.
