Tobias Grosser 1eedb67fa6 We do not support alias checks for base pointers defined inside the SCoP
The run-time alias check places code that involves the base pointer at the
beginning of the SCoP. This breaks if the base pointer is defined inside the
SCoP. Hence, we can only create a run-time alias check if we are sure the base
pointer is not an instruction defined inside the scop. If it is we refuse to
handle the SCoP.

This commit should unbreak most of our current LNT failures.

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.
