Serguei Katkov edf3c8292b [SCEV] Do not insert if it is already in cache ... This is fix for the crash caused by ScalarEvolution::getTruncateExpr. It expects that if it checked the condition that SCEV is not in UniqueSCEVs cache in the beginning that it will not be there inside this method. However during recursion and transformation/simplification for sub expression, it is possible that these modifications will end up with the same SCEV as we started from. So we must always check whether SCEV is in cache and do not insert item if it is already there.
