gh-134768: Fix definition of `mt_continue_should_break()` (GH-134769)
In 121ed71f4e, mt_continue_should_break
was changed to be guarded by `Py_DEBUG`, but it's used in `compress_mt_continue_lock_held`
with just `assert`, so it needs to be available when `NDEBUG` is undefined
too.
`Py_DEBUG` implies `NDEBUG` is undefined, so we can check just that.

Contrary to the current docs, ast.Constant will never hold containers
such as frozenset or tuple; the Python parser only emits it for simple
literals.
For precision, add the exact list of types that may be contained in an
ast.Constant.

gh-132775: Fix _PyFunctIon_VerifyStateless() ()
The problem we're fixing here is that we were using PyDict_Size() on "defaults",
which it is actually a tuple. We're also adding some explicit type checks.
This is a follow-up to gh-133221/gh-133528.

This adds a warning about the possibly-missing NUL terminator, but in a way
that doesn't make it sound like a bug/wart.

gh-133711: Fix test_regrtest for PYTHONUTF8=1 (GH-134839)
Use "backslashreplace" error handler to decode stdout and stderr.
Example:
vstinner@WIN C:\victor\python\main\build\test_python_worker_8360\x91>
"C:\victor\python\main\PCbuild\amd64\python_d.exe" -m test
--fast-ci --slow-ci --testdir
C:\Users\vstinner\AppData\Local\Temp\tmp0t59e8da
test_regrtest_noop1 test_regrtest_noop2 test_regrtest_noop3
test_regrtest_noop4
Notice the "\x91" byte at the end of the first line: it's the
non-ASCII U+00E6 character encoded to the OEM cp437 code page.

Fix typing.TYPE_CHECKING docs to reflect PEP 649. (GH-134813)
typing.TYPE_CHECKING should no longer steer users towards

This is the same underlying bug as gh-130519. The destructor may call

gh-119180: Updates to PEP 649/749 docs (GH-134640)
- Mention (again) that `type.__annotations__` is unsafe. It is now safe
when using only classes defined under PEP 649 semantics, but not with
classes defined using `from __future__ import annotations`.
- Mention that annotations on instances no longer work. There was already
an issue about this.
- Mention the general changes in the "Porting to Python 3.14" section.
- `annotationlib` was proposed by PEP-749, not PEP-649.
