Tobias Grosser 428b3e48e2 ScopDetection: Improve printing of alias sets 
We now show the all members of the alias set that may couse possible aliasing.
In case a alias set member is not a named instruction (unnamed instructions or
constant expressions), we show the expression itself.

This improves our error message

from:

  Possible aliasing for value: .reg2mem

to:

  Possible aliasing: ".reg2mem",
                     "[0 x double]* inttoptr (i64 47255179264 to [0 x double]*)

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.
