Summary

Please do not try to review this patch, I'm putting it up so I can chip
away at this and remove all the hacks. Once that is done, I'll split it up
into managable patches.

This patch teaches:

Polly to interpret multidimensional index expressions.
ScopArrayInfo to use a ShapeInfo class to store info based on size / stride based representation.
PPCGCodeGen to codegen for these strided arrays.
IslNodeBuilder, IslExprBuilder, et. al about strided arrays.
