[RFC] Heuristics to throttle the complette unrolling

Hi, for past week or two I was playing with ways to throttle down the complette unrolling heuristics. I made complette unroller to use the tree-ssa-loop-niter upper bound and unroll even in non-trivial cases and this has turned out to increase number of complettely unrolled loops by great amount,
