>
> If the input to V2 expression translation is context-independent and foldable
> (see [PR #51282|https://github.com/apache/spark/pull/51282]), we perform
> constant folding on the input and use the evaluated result.
>
> For example:
> * 1 + 1 becomes 2
> * a < log2(8) becomes a < 3.0
>
> This change broadens the coverage of V2 expression translation.
