Decouple SCoP building logic from pass

  Created a new pass ScopInfoRegionPass. As name suggests, it is a
  region pass and it is there to preserve compatibility with our
  existing Polly passes.  ScopInfoRegionPass will return a SCoP object
  for a valid region while the creation of the SCoP stays in the
  ScopInfo class.
