bpo-37148: Fix asyncio test that check for warning when running the test suite with huntleaks (GH-13800)

This reverts commit 396e0a8d.

Revert "bpo-35621: Support running subprocesses in asyncio when loop is executed in non-main thread (#13630)" (GH-13793)



https://bugs.python.org/issue35621

--with-pydebug is commonly used to find memory leaks.
But opcache makes it harder.
So disable opcache when Py_DEBUG is defined.

Add BaseEventLoop.wait_executor_on_close attribute: true by default.

loop.close() now waits for the default executor to finish by default.
Set loop.wait_executor_on_close attribute to False to not wait for
the executor.

Revert "bpo-33608: Factor out a private, per-interpreter _Py_AddPendingCall(). (gh-13714)" (GH-13780)

This reverts commit 6a150bca.

Replace asyncio.set_event_loop() with TestCase.set_event_loop() of
test_asyncio.utils: this method calls TestCase.close_loop() which
waits until the executor completes, to avoid leaking dangling
threads.

Inherit from test_asyncio.utils.TestCase rather than
unittest.TestCase.

* Credit myself and others.
* Complete asyncio changes.

This code was for deoptimization, which is removed from
PR-12884.

This patch implements per opcode cache mechanism, and use it in
only LOAD_GLOBAL opcode.

Based on Yury's opcache3.patch in bpo-26219.

Modify test_coroutines, test_cprofile, test_generators, test_raise,
test_ssl and test_yield_from to use
support.catch_unraisable_exception() rather than
support.captured_stderr().

test_thread: remove test_save_exception_state_on_error() which is now
updated. test_unraisable_exception() checks that sys.unraisablehook()
is called to handle _thread.start_new_thread() exception.

test_cprofile now rely on unittest for test discovery: replace
support.run_unittest() with unittest.main().

Apologies for the earlier hasty attempt.

test_coroutines: test_unawaited_warning_when_module_broken() now uses
support.check_warnings() to catch expected RuntimeWarning.

The main slot assignment loop is now if-else if ladder, making the
control flow clearer.
