The pass manager will be launched by the vectorizer pass, so in that sense it is tied to the vectorizer. But I see your point. Ideally there should be a generic pass manager for Sandbox IR passes. I think we could accommodate for that if Sandbox IR ended up being used by other transformations too. In that case we could move the Pass/PassManager files to a generic directory.
