URL: https://github.com/apache/beam/issues/20354
'NaN \== NaN' for ZetaSQL DOUBLE type should be false. But it would hit into
the Calcite operation simplification block to be simplified to 'null or NaN is
not null' in Calcite. This would miscalculate the expression to be true.
Currently, we add an additional random parameter for the wrapper function of
NaN, to avoid
triggering Calcite operation simplification. But it is only a temporary
solution.
Once the Calcite version updated, we should replace this method by
overriding isDeterministic() for RexNode to make it false.
