I think you are right.  However, Polly might be useful as one layer in a
dependence tester.  I haven't thought too deeply about it but polyhedral
analysis can do some pretty cool things.

I'm really not clear on what something like CLooG would do with the
linear recurrence example.  But the analysis side of Polly might be
quite useful.
