Assertion failure when specializing functions with too many __defaults__ #105840
Description
When specializing some Python calls, we assert that we don't have more defaults than we have arguments. This isn't always true, though:
>>> def f():
... pass
...
>>> f.__defaults__ = (None,)
>>> for _ in range(2):
... f()
...
python: Python/specialize.c:1650: specialize_py_call: Assertion `defcount <= argcount' failed.
