[Cython] Cython test coverage

[Stefan Behnel]

Hi,

I just ran coverage.py over the test suite.

$ python -m coverage -x runtests.py
[...]
$ python -m coverage -r Cython/Compiler/*.py

Quite ok, but also quite a bit missing. Especially Parsing.py, Nodes.py and
ExprNodes.py do not make me feel very comfortable.

I would assume error testing to be a major factor here. We test a lot of
working code, but little broken code.
