`std::set::insert` isn't exposed into Swift, because it returns an instance of an unsafe type. This change adds a Swift overload of `insert` for `std::set` and `std::unordered_set` that has the return type identical to `Swift.Set.insert`: a tuple of `(inserted: Bool, memberAfterInsert: Element)`. rdar://111036912
