Support non-affine access functions in Polly.
...
In case we can not analyze an access function, we do not discard the SCoP, but
assume conservatively that all memory accesses that can be derived from our base
pointer may be accessed.

Parameters can be complex SCEV expressions, but they can also be single scalar

It may happen that we generate the code of a basic block from the original

I am planning to eliminate the TempScopInfo pass. To simplify this I remove

The interchange pass is currently strongly tested and furthermore ment to be
replaced by the general scheduling optimizer. Reductions itself can later
be added easily.
