Improve batching for entity updates or deletes that use secondary tables
------------------------------------------------------------------------

                 Key: HHH-5797
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5797
             Project: Hibernate Core
          Issue Type: Improvement
          Components: core
            Reporter: Gail Badner
             Fix For: 4.x


Currently, batching is only used for update/delete statements made to an entity's primary table (subject to other conditions). Batching is not used for update/delete statements on secondary tables.

1) if an entity has *any* secondary tables with optional="true, do not use batching for updating/deleting any of the entity's (primary or secondary) tables
2) if all of an entity's secondary tables are non-optional (e.g. "joined" subclass, all "joined" tables have optional="false"), then use batching for updates/deletes to all (primary and secondary) tables
