Thank you @marmbrus to review this.
All of primitive constant null value actually will not find a match, and
will be considered as normal ObjectInspector, this won't bring the incorrect
result. But the `ConstantObjectInspector` is definitely a way of optimization,
at least we can avoid `wrap`ing the Literal arguments for UDFs. I have plan to
do this with follow ups.
