Increase support.LOOPBACK_TIMEOUT from 5 to 10 seconds. Also increase
the timeout depending on the --timeout option. For example, for a
test timeout of 40 minutes (ARM Raspbian 3.x), use LOOPBACK_TIMEOUT
of 20 seconds instead of 5 seconds before.

gh-109972: Enhance test_gdb (#110026)
* Split test_pycfunction.py: add test_cfunction_full.py.
  Split the function into the following 6 functions. In verbose
  mode, these "pycfunction" tests now log each tested call.

  * test_pycfunction_noargs()
  * test_pycfunction_o()
  * test_pycfunction_varargs()
  * test_pycfunction_varargs_keywords()
  * test_pycfunction_fastcall()
  * test_pycfunction_fastcall_keywords()

* Move get_gdb_repr() to PrettyPrintTests.
* Replace DebuggerTests.get_sample_script() with SAMPLE_SCRIPT.
* Rename checkout_hook_path to CHECKOUT_HOOK_PATH.
* Rename gdb_version to GDB_VERSION_TEXT.
* Replace (gdb_major_version, gdb_minor_version) with GDB_VERSION.
* run_gdb() uses "backslashreplace" error handler instead of "replace".
* Add check_gdb() function to util.py.
* Enhance support.check_cflags_pgo(): check also for sysconfig
  PGO_PROF_USE_FLAG (if available) in compiler flags.
* Move some SkipTest checks to test_gdb/__init__.py.
* Elaborate why gdb cannot be tested on Windows: gdb doesn't support
  PDB debug symbol files.

gh-103053: Skip test_freeze_simple_script() on PGO build (#109591)
Skip test_freeze_simple_script() of test_tools.test_freeze if Python
is built with "./configure --enable-optimizations", which means with
Profile Guided Optimization (PGO): it just makes the test too slow.
The freeze tool is tested by many other CIs with other (faster)
compiler flags.

test.pythoninfo now gets also get_build_info() of
test.libregrtests.utils.

gh-109039: Branch prediction for Tier 2 interpreter (#109038)
This adds a 16-bit inline cache entry to the conditional branch instructions POP_JUMP_IF_{FALSE,TRUE,NONE,NOT_NONE} and their instrumented variants, which is used to keep track of the branch direction.

Each time we encounter these instructions we shift the cache entry left by one and set the bottom bit to whether we jumped.

Then when it's time to translate such a branch to Tier 2 uops, we use the bit count from the cache entry to decided whether to continue translating the "didn't jump" branch or the "jumped" branch.

The counter is initialized to a pattern of alternating ones and zeros to avoid bias.

The .pyc file magic number is updated. There's a new test, some fixes for existing tests, and a few miscellaneous cleanups.

* Add attributes to Regrtest and RunTests:

  * gc_threshold
  * memory_limit
  * python_cmd
  * use_resources

* Remove WorkerJob class. Add as_json() and from_json() methods to
  RunTests. A worker process now only uses RunTests for all
  parameters.
* Add tests on support.set_memlimit() in test_support. Create
  _parse_memlimit() and also adds tests on it.
* Remove 'ns' parameter from runtest.py.

gh-109045: Remove remaining LIMITED_API_AVAILABLE checks in tests (#109046)
Commit 13a00078b8 (#108663) made all
Python builds compatible with the Limited API, and removed the
LIMITED_API_AVAILABLE flag.  However, some tests were still checking
for that flag, so they were now being incorrectly skipped.  Remove
these checks to let these tests run again.

gh-108834: regrtest reruns failed tests in subprocesses (#108839)
When using --rerun option, regrtest now re-runs failed tests
in verbose mode in fresh worker processes to have more
deterministic behavior. So it can write its final report even
if a test killed a worker progress.

Add --fail-rerun option to regrtest: exit with non-zero exit code
if a test failed pass passed when re-run in verbose mode (in a
fresh process). That's now more useful since tests can pass
when re-run in a fresh worker progress, whereas they failed
when run after other tests when tests are run sequentially.

Rename --verbose2 option (-w) to --rerun. Keep --verbose2 as a
deprecated alias.

Changes:

* Fix and enhance statistics in regrtest summary. Add "(filtered)"
  when --match and/or --ignore options are used.
* Add RunTests class.
* Add TestResult.get_rerun_match_tests() method
* Rewrite code to serialize/deserialize worker arguments as JSON
  using a new WorkerJob class.
* Fix stats when a test is run with --forever --rerun.
* If failed test names cannot be parsed, log a warning and don't
  filter tests.
* test_regrtest.test_rerun_success() now uses a marker file, since
  the test is re-run in a separated process.
* Add tests on normalize_test_name() function.
* Add test_success() and test_skip() tests to test_regrtest.

regrtest computes statistics (#108793)
test_netrc, test_pep646_syntax and test_xml_etree now return results
in the test_main() function.

Changes:

* Rewrite TestResult as a dataclass with a new State class.
* Add test.support.TestStats class and Regrtest.stats_dict attribute.
* libregrtest.runtest functions now modify a TestResult instance
  in-place.
* libregrtest summary lists the number of run tests and skipped
  tests, and denied resources.
* Add TestResult.has_meaningful_duration() method.
* Compute TestResult duration in the upper function.
* Use time.perf_counter() instead of time.monotonic().
* Regrtest: rename 'resource_denieds' attribute to 'resource_denied'.
* Rename CHILD_ERROR to MULTIPROCESSING_ERROR.
* Use match/case syntadx to have different code depending on the
  test state.

gh-108634: Py_TRACE_REFS uses a hash table (#108663)
Python built with "configure --with-trace-refs" (tracing references)
is now ABI compatible with Python release build and debug build.
Moreover, it now also supports the Limited API.

Change Py_TRACE_REFS build:

* Remove _PyObject_EXTRA_INIT macro.
* The PyObject structure no longer has two extra members (_ob_prev
  and _ob_next).
* Use a hash table (_Py_hashtable_t) to trace references (all
  objects): PyInterpreterState.object_state.refchain.
* Py_TRACE_REFS build is now ABI compatible with release build and
  debug build.
* Limited C API extensions can now be built with Py_TRACE_REFS:
  xxlimited, xxlimited_35, _testclinic_limited.
* No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2()
  functions to PyModule_Create2TraceRefs() and
  PyModule_FromDefAndSpec2TraceRefs().
* _Py_PrintReferenceAddresses() is now called before
  finalize_interp_delete() which deletes the refchain hash table.
* test_tracemalloc find_trace() now also filters by size to ignore
  the memory allocated by _PyRefchain_Trace().

Test changes for Py_TRACE_REFS:

* Add test.support.Py_TRACE_REFS constant.
* Add test_sys.test_getobjects() to test sys.getobjects() function.
* test_exceptions skips test_recursion_normalizing_with_no_memory()
  and test_memory_error_in_PyErr_PrintEx() if Python is built with
  Py_TRACE_REFS.
* test_repl skips test_no_memory().
* test_capi skisp test_set_nomemory().

gh-106320: Remove private _PyErr_ChainExceptions() (#108713)

  (pycore_pyerrors.h).
* Move the private _PyErr_SetFromPyStatus() to the internal C API
  (pycore_initconfig.h).
* No longer export the _PyErr_ChainExceptions() function.
* Move run_in_subinterp_with_config() from _testcapi to
  _testinternalcapi.

GH-86275: Implementation of hypothesis stubs for property-based tests, with zoneinfo tests (#22863)
These are stubs to be used for adding hypothesis (https://hypothesis.readthedocs.io/en/latest/) tests to the standard library.

When the tests are run in an environment where `hypothesis` and its various dependencies are not installed, the stubs will turn any tests with examples into simple parameterized tests and any tests without examples are skipped.

It also adds hypothesis tests for the `zoneinfo` module, and a Github Actions workflow to run the hypothesis tests as a non-required CI job.

The full hypothesis interface is not stubbed out — missing stubs can be added as necessary.
