Previously, to produce the correct output expressions for the root plan fragment before a table sink, InsertStmt would reorder the result expressions for the query statement at the plan root. This had stopped working for SelectStmts (and test coverage didn't catch that). Now InsertStmt produces its own output expressions that can substitute for the originals from the query statement, and the planner uses those instead. All query tests for column reordering have been duplicated to use SELECT expressions.
