The attributes are copied from the item for which the trait impl is derived
I think now we can close these two issues:
https://github.com/rust-lang/rust/issues/13054 - `allow`, `deny` etc. were already copied, now `stable` and `unstable` are copied as well.
https://github.com/rust-lang/rust/issues/18969 - I'm not sure this is needed, insta-stability were good enough so far, copied stability will be better. Nonetheless, it can be subsumed by some more general mechanism for supplying arbitrary not necessarily stability related attributes (for example `inline`) to derived impls and their methods (I haven't found an open issue for such mechanism).

Rollup merge of #29027 - steveklabnik:iter_docs, r=manishearth
Due to the way iterators work, the std::iter module is chock full of
structs that you, humble Rust programmer, will never actually use.
However, they have URLs, and therefore get linked to, because they are
real structs that do exist.
So, rather than just have a tiny sentence about each one of them,
this patch adds links back to the functions and methods on Iterator
which actually create the structs, where helpful documentation already
exists.

1. It makes `Arc<T>` and `Rc<T>` covariant in `T`.
2. It causes the compiler to reject code that was unsound with respect
to dropck. See compile-fail/issue-29106.rs for an example of code that
no longer compiles. Because of this, this is a [breaking-change].
