Fix build_grouping_chain() to not clobber its input lists. There's no good reason for stomping on the input data; it makes the logic in this function no simpler, in fact probably the reverse. And it makes it impossible to separate path generation from plan generation, as I'm working towards doing; that will require more than one traversal of these lists.
