Replace has_multiple_baserels() with a bitmap test on all_baserels. Since we added the PlannerInfo.all_baserels set, it's not really necessary to grovel over the rangetable to count baserels in the current query. So let's drop has_multiple_baserels() in favor of a bms_membership() test. This might be microscopically faster, but the main point is to remove some unnecessary code.
