It vectorizes just memory operations, unlike the SLPVectorizer which starts at stores and tries to vectorize the complete operation chain up to the loads.

It don’t think it should have a more generic name now since it isn’t added to the generic pass pipeline and is just in the backend. I’m not 100% sure this is the right pass order to run this and different targets probably want it in a different place.
