… r=cjgillot Introduce `subst_iter` and `subst_iter_copied` on `EarlyBinder` Makes working with bounds lists a bit easier, which I seem to do a lot. Specifically, means that we don't need to do `.transpose_iter().map(|(pred, _)| *pred)` every time we want to iterate through an `EarlyBinder<&'tcx [(Predicate, Span)]>` (and even then, still have to call `subst` later), which was a very awkward idiom imo.
