Thanks for reviewing the patch.
For now the answer is no, LoopVectorizer will still create RTCs. We are only preventing the fall back original loop by polly from getting versioned/vectorized by LoopVectorizer. But eventually the goal is to remove such common checks and append only if there are any additional checks from Loop Vectorizer.
