Johannes Doerfert e1fa6da356 [FIX] Create location if a needed value was not yet demoted
This allows the code generation to continue working even if a needed
  value (that is reloaded anyway) was not yet demoted. Instead of
  failing it will now create the location for future demotion to memory
  and load from that location. The stores will use the same location and
  by construction execute before the load even if the textual order in
  the generated AST is otherwise.

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.
