Johannes Doerfert be9c91173f [Refactor] Use only one BlockGenerator for a SCoP
This change has two main purposes:
    1) We do not use a static interface to hide an object we create and
       destroy for every basic block we copy.
    2) We allow the BlockGenerator to store information between calls to
       the copyBB method. This will ease scalar/phi code generation
       later on.

  While a lot of method signatures were changed this should not cause
  any real behaviour change.

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.
