Johannes Doerfert e69e1141d9 Introduce the ScopExpander as a SCEVExpander replacement ...

The SCEVExpander cannot deal with all SCEVs Polly allows in all kinds
  of expressions. To this end we introduce a ScopExpander that handles
  the additional expressions separatly and falls back to the
  SCEVExpander for everything else.
