> MapType should not support equality & ordering

> MapType today happened to support equality comparison because we use Scala
> maps under the hood. However, map type should not support equality, hash, or
> ordering (i.e. cannot be used as join keys, grouping keys, or in
> equality/ordering tests).
> We should throw the appropriate analysis exception for these cases.
