Tobias Grosser a187964bac 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.

Tobias Grosser e5e171eadd Reuse the old BaseAddress checking in SCEVValidator to make sure that no base 
address is part of the access function. Also remove unused special cases that
were necessery when the base address was still contained in the access function

Tobias Grosser e4e2f7b16e TempScop: Rename SCEVAffFunc to IRAccess 
The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

Tobias Grosser 60b54f19e6 Detect Parameters directly on the SCEV. 
Instead of using TempScop to find parameters, we detect them directly
on the SCEV. This allows us to remove the TempScop parameter detection
in a subsequent commit.

This fixes a bug reported by Marcello Maggioni <hayarms@gmail.com>

Tobias Grosser 604c981f40 Temporarily remove reduction support and interchange pass 
I am planning to eliminate the TempScopInfo pass. To simplify this I remove
some features that may later be added to the ScopInfo pass.

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.
