### What changes were proposed in this pull request? This is a followup of #23388 . #23388 has an issue: it doesn't handle subquery expressions and assumes they will be turned into joins. However, this is not true for non-correlated subquery expressions. This PR fixes this issue. It now doesn't skip `Subquery`, and subquery expressions will be handled by `OptimizeSubqueries`, which runs the optimizer with the subquery. Note that, correlated subquery expressions will be handled twice: once in `OptimizeSubqueries`, once later when it becomes join. This is OK as `NormalizeFloatingNumbers` is idempotent now. ### Why are the changes needed? fix a bug ### Does this PR introduce _any_ user-facing change? yes, see the newly added test. ### How was this patch tested? new test Closes #28785 from cloud-fan/normalize.
