4b3a878e - [Polly] Disable vectorization for Polly's fallback loops (#119188)

[Polly] Disable vectorization for Polly's fallback loops (#119188) The patch sets the vectorization metadata to false for Polly's fallback loops. These are the loops executed when RTCs fail. This minimizes the multiple loop versioning carried out by Polly and subsequently by the Loop Vectorizer. --------- Co-authored-by: Michael Kruse <github@meinersbur.de>
