Hi Tobias-

Let me relook at Preston's patch and think of what I need in a similar analysis for dependence. I will get back to you once I am comfortable.

Polly is already divided into analysis and transformation passes. 
However, the interface is currently specific to the needs of polyhedral 
optimizers. If there is interest to use e.g. the analyzer
part of Polly within core LLVM, we could adapt the interface to our 
needs. We could e.g. think of an interface similar to Preston's 
dependency analysis.
