[PATCH] D17477: [Polly] [RFC] Allow the client of DependenceInfo to obtain dependences at different granularities.

I am not convinced per-granularity passes are the right thing. I would 
personally probably just add functions to ask for the different 
dependences and build them on-demand when they are requested to avoid 
the permanent overhead of eagerly computing all dependences.

Best,
