Is there a reason why these need to be removed? When we eventually bring up GlobalISel for SVE, we may want these additional type information for the importer. We see cases today of some NEON patterns being importable once the types are specified.

I'm not blocking this since it's not even certain that these patterns will be problematic for the importer.
