SPARK-2226: [SQL] transform HAVING clauses with aggregate expressions that aren't in the aggregation list
This change adds an analyzer rule to
1. find expressions in `HAVING` clause filters that depend on unresolved attributes,
2. push these expressions down to the underlying aggregates, and then
3. project them away above the filter.
It also enables the `HAVING` queries in the Hive compatibility suite.
