[GSoC 2016] New function pass DependenceInfoWrapperPass
This patch addresses:
- A new function pass to compute polyhedral dependences. This is required to avoid the region pass manager.
- Stores a map of Scop to Dependence object for all the scops present in a function. By default, access wise dependences are stored.
