PlannedStmt->resultRelations was an integer list of range table indexes
because at the time it was added (to Query), the Bitmapset data type did
not yet exist in Postgres.
0f4c170cf3 added a Bitmapset of result relations, so remove the integer
list of RTIs and use the more compact resultRelationRelids.
