Dimitris Tsirogiannis ccf1f8f73f IMPALA-2734: Correlated EXISTS subqueries with HAVING clause return wrong results ...

This commit fixes an issue where wrong results are returned if an EXISTS subquery
contains a HAVING clause and non-equality correlated binary predicates. This case does
not have a valid rewrite as the HAVING clause needs to be applied after the correlated
predicates have been evaluated. With this fix, we detect cases like this and throw an
AnalysisException.
