[PATCH] [Polly] Map isl_ast for nodes to LLVM Loops

[Johannes Doerfert]

As soon as the last testcase is resolved this should be good to go.

----------------
@grosser Do you have a good idea how we can spot and react when the isl AST creation removes dimensions?
         I think we can spot it by counting but I don't know what to do when we spotted it. Is there any rule
         in how isl can remove dimensions (e.g., only from outer to inner)?
