IGNORE: Project uops forever

[gvanrossum]

(This is a variant of #107793 with -Xuops always enabled, to see if that would pass all tests. We should not merge this, as -Xuops is currently slower than the default interpreter.)

At least one of the test failures (there aren't very many), in test_traceback.py, could be due to the missing _Py_EnterRecursivePy call:

    def test_long_context_chain(self):
        def f():
            try:
                1/0
            except:
                f()

        try:
            f()
        except RecursionError as e:
            exc_obj = e
        else:
            self.fail("Exception not raised")

Although there's probably more going on, since the bug is rather shy: I can repro it only by running the entire test_traceback.py file, not by selectively only running this one test. (Possibly because the other tests contribute to the stack overflow.) Anyway, this is enough to keep gh-107793 and gh-107925 in draft mode until I've figured out how to add the recursion checks back.
