> UnresolvedRelation has a second argument named "alias", for assigning the 
> relation an alias. I think we can actually remove it and replace its use with 
> a SubqueryAlias.
> This would actually simplify some analyzer code to only match on 
> SubqueryAlias. For example, the broadcast hint pull request can have one 
> fewer case https://github.com/apache/spark/pull/16925/files.
