Review Comment:
`arg_null_map` was updated in this line, and was used be code after this
line, then you removed this logic. Why does this function still work?

do not modify code like this if this pr just wants to do refactor on

Review Comment:
same problem with `RangeImplUtil`, it seems you remove some update logic to
`res_null_map`, but actually `res_null_map` is still being used in the code.
