Besides class, function and file names, we also change the command line option

I just learned that target triples prevent test cases to be run on other
architectures. Polly test cases are until now sufficiently target independent
to not require any target triples. Hence, we drop them.

Scops that only read seem generally uninteresting and scops that only write are

been tested for a long time. We now drop the support the non-scev-based code
generation.
