polyjit: only perform scop detection at compile-time.

This restricts Polly to ScopDetection only. We may trigger weird bugs
because of keep-going in polly during modelling. This commit requires
to generate a new baseline that runs only polly without jit scops
in PolyJIT. This will be subject of a later commit.
