This function has been semi-deprecated ever since we invented bms_next_member(). Its habit of scribbling on the input bitmapset isn't great, plus for sufficiently large bitmapsets it would take O(N^2) time to complete a loop. Now we have the additional problem that reducing the input to empty while leaving it still accessible would violate a planned invariant. So let's just get rid of it, after updating the few extant callers to use bms_next_member(). Patch by me; thanks to Nathan Bossart and Richard Guo for review.
