1ce77ff600 Merge pull request #2507 from tausbn/python-fix-infinite-tuple-tostring 
Python: Fix divergence in tuple `toString`.

3cebffe820 Python: Fix divergence in tuple toString. 
Our definition of `toString` for the internal tuple objects we create during the
points-to analysis may have been a _tad_ too ambitious. In particular, it can
easily lead to non-termination, e.g. using the following piece of code:

```python
x = ()
while True:
    x = (x, x)
```

This commit cuts off the infinite recursion by replacing _nested_ tuples with
the string "...". In particular this means even non-recursive tuples will be cut
off at that point, so that the following tuples

```python
(1, "2")
((3, 4), [5, 6])
(1, 2, 3, 4, 5)
```

Get the following string representations.

```
"(int 1, '2', )"
"(..., List, )"
"(int 1, int 2, int 3, 2 more...)"
```

3db551d6bc Python: Use variables in collection-taint test 
They are not tainted in assignment, only in use.

I also adopted an attempt at a better test-setup, where it's easy to see if
everything is the way you hoped for, instead of browsing through 100 of lines of
taint-step output :P
