           Summary: [Polly] Timeout during scop construction due to overly
                    complex sets being formed

Test case

Polly with 252451 times out when running polly-opt -polly-process-unprofitable
timeout.ll

It seems that the sets we are creating during scop construction are becoming
very complex. We could probably timeout on this, but my feeling is that at
least for this test case we should be able to compute the scop represenation
more efficiently?
