as LIKE. I oversimplified this code when removing support for plan-time determination of index operator lossiness back in April --- I had thought create_bitmap_subplan could stop returning two separate lists of qual conditions, but it still must so that we can treat special operators correctly in create_bitmap_scan_plan. Per report from Rushabh Lathia.
