Daniil Fukalov cb1b606dcd [SCEV] limit recursion depth of CompareSCEVComplexity 
Summary:
CompareSCEVComplexity goes too deep (50+ on a quite a big unrolled loop) and runs almost infinite time.

Added cache of "equal" SCEV pairs to earlier cutoff of further estimation. Recursion depth limit was also introduced as a parameter.
