Update Tuning Guide documentation to reflect the new static IN list transformation that occurs
as a result of DERBY-47.
-----------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-2499
                 URL: https://issues.apache.org/jira/browse/DERBY-2499
             Project: Derby
          Issue Type: Sub-task
          Components: Documentation
    Affects Versions: 10.3.0.0
            Reporter: A B
            Priority: Minor


DERBY-47 changed the static rewrite logic for IN lists.  Whereas we used to create a BETWEEN
predicate for IN-lists that contain all constants and then use that predicate to limit the
scan, we now create a "probe predicate" for IN-lists that contain all constants *and/or* parameter
nodes and then use that new predicate to perform execution-time probing.

The documentation in the Tuning Guide needs to be updated to reflect this change in behavior.
