Johannes Doerfert 77bd5ae3d9 [Fix] Allow pointer types as access elements and compare them correctly
This fixes two problems which are usualy caused together:
    1) The elements of an isl AST access expression could be pointers
       not only integers, floats and vectores thereof.
    2) The runtime alias checks need to compare pointers but if they
       are of a different type we need to cast them into a "max" type
       similar to the non pointer case.

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.
