        Fixed bug #12144.
        Added an optimization that avoids key access with null keys for the 'ref'
        method when used in outer joins. The regilar optimization with adding
        IS NOT NULL expressions is not applied for outer join on expressions as
        the predicates of these expressions are not pushed down in 4.1.
      null_key.result, null_key.test:
        Added a test case for bug #12144.
