This looks like it also disallows ops with regions inside the atomic region. While I don't see an immediate use-case for it, I also don't think we should just ban them. Maybe walk the op instead and check for side effects?

It would be extra nice if we could get a note where the side-effecting operation is. But that is icing on the cake.

Having the emitOpError on the operation inside the walk would probably get this achieved nicely I think?
