Subject: [PATCH 1/3] Fix test expectations for Python 3.9 AST changes
Fixes the following two tests under Python 3.9:
FAILED ropetest/refactor/patchedasttest.py::PatchedASTTest::test_ext_slice_node - AssertionError: Node <ExtSlice> cannot be found
FAILED ropetest/refactor/patchedasttest.py::PatchedASTTest::test_simple_subscript - AssertionError: False is not true : Expected <Index> but was <Constant>
The ast module in Python 3.9 has some API changes. Quoting [1]:
Simplified AST for subscription. Simple indices will be represented
by their value, extended slices will be represented as tuples.
Index(value) will return a value itself, ExtSlice(slices) will
return Tuple(slices, Load()). (Contributed by Serhiy Storchaka in
bpo-34822.)

Subject: [PATCH 2/3] Handle AST.expr in _Subscript()
The ast module in Python 3.9 has some API changes. Quoting [1]:
Simplified AST for subscription. Simple indices will be represented
by their value, extended slices will be represented as tuples.
Index(value) will return a value itself, ExtSlice(slices) will

[1] https://docs.python.org/3/whatsnew/3.9.html#changes-in-the-python-api
isinstance(thing, ast.Index) always return false in Python >= 3.9, so we
need to handle... whatever the value is now. ast.expr catches 20 of the
remaining 24 failures. The remaining 4 are resolved in the next patch.
Fixes: #299
