Johannes Doerfert 0fe35dd088 [Fix] Rewire the Region after a unconditional entry edge is created
We use SplitEdge to split a conditional entry edge of the SCoP region.
  However, SplitEdge can cause two different situations (depending on
  whether or not the edge is critical). This patch tests
  which one is present and deals with the former unhandled one.

  It also refactors and unifies the case we have to change the basic
  blocks of the SCoP to new ones (see replaceScopAndRegionEntry).

Polly - Polyhedral optimizations for LLVM
-----------------------------------------
http://polly.llvm.org/

Polly uses a mathematical representation, the polyhedral model, to represent and
transform loops and other control flow structures. Using an abstract
representation it is possible to reason about transformations in a more general
way and to use highly optimized linear programming libraries to figure out the
optimal loop structure. These transformations can be used to do constant
propagation through arrays, remove dead loop iterations, optimize loops for
cache locality, optimize arrays, apply advanced automatic parallelization, drive
vectorization, or they can be used to do software pipelining.
