After this check-in the build in one of my environments (windows) fails and
this results in many test failures.

> NOT elimination for CASE expressions seems to be broken. Take this example:
> {noformat}
> ij> select * from sysibm.sysdummy1 where not ( case when ibmreqd = 'Y' then
> true else true end );
> IBM&
> ----
> Y
> 1 row selected
> {noformat}
> Both branches of the CASE expression evaluate to TRUE, so one would expect
> the predicate "not ( case ... )" to evaluate to FALSE, and the query should
> return an empty result.
