Initially SLP vectorizer replaced all going-to-be-vectorized instructions with Undef values. It may break ScalarEvaluation and may cause a crash. Reworked SLP vectorizer so that it does not replace vectorized instructions by UndefValue anymore. Instead vectorized instructions are marked for deletion inside if BoUpSLP class and deleted upon class destruction.
