    [SPARK-8104][SQL] auto alias expressions in analyzer

    Currently we auto alias expression in parser. However, during parser phase we don't have
enough information to do the right alias. For example, Generator that has more than 1 kind
of element need MultiAlias, ExtractValue don't need Alias if it's in middle of a ExtractValue
