[PATCH] D49024: [Polly] [WIP] Introduce ShapeInfo into polly for sizes and strides.

[SAHIL GIRISH YERAWAR via Phabricator via llvm-commits]

cs15btech11044 added a comment.

Next Steps:

- There was a need to introduce a new kind of value map for this to work, a map from `const SCEV * -> Value *`. I hugely dislike this design, and would love to change this.

- Ideally the ScopArrayInfo should only save pw_aff. However, since we _do_ allow nonaffine indexing, this is not very sane. We need some point  in the design space which is not so painful to work with.

- We need to test the stride code path from the chapel source code.
