Fix ExecSubPlan to handle nulls per the SQL spec --- it didn't combine
nulls with non-nulls using proper three-valued boolean logic.  Also clean
up ExecQual to make it clearer that ExecQual *does* follow the SQL spec
for boolean nulls.  See '[BUGS] (null) != (null)' thread around 10/26/99
for more detail.
