even we modify it to hold the results of subexpressions in member
variables, the above code example should not work under wholestage codegen.
The above code example is similar to non wholestage codegen subexpression
elimination in fact, which is also using functions to wrap subexpression
evaluations.
But for wholestage codegen, as we might evaluate expressions against input
row or local variables, the function approach can't work due to these local
variables.
