Johannes Doerfert 8031238017 [GSoC] Add PolyhedralInfo pass - new interface to polly analysis
Adding a new pass PolyhedralInfo. This pass will be the interface to Polly.
  Initially, we will provide the following interface:
    - #IsParallel(Loop *L) - return a bool depending on whether the loop is
                             parallel or not for the given program order.

Tobias Grosser f4ee371e60 tests: Drop -polly-detect-unprofitable and -polly-no-early-exit
These flags are now always passed to all tests and need to be disabled if
not needed. Disabling these flags, rather than passing them to almost all
tests, significantly simplfies our RUN: lines.

Tobias Grosser d1e33e7061 ScopDetection: Only detect scops that have at least one read and one write
Scops that only read seem generally uninteresting and scops that only write are
most likely initializations where there is also little to optimize.  To not
waste compile time we bail early.
