Alex Behm 3e770405e3 IMPALA-5504: Fix TupleIsNullPredicate evaluation. ...

There was a bug in the BE evaluation logic of the
TupleIsNullPredicate which could lead to wrong results
for certain plan shapes.

A TupleIsNullPredicate should evaluate to true only if
all specified tuples are NULL. This was always the intent
of the FE and is also documented in the BE as the required
behavior.

Testing:
- Added regression test
- Core tests passed
