Lifetimes: Updates to incorporate NLL
...
* Updated the explanations around lifetimes a bit.
* Made sure the examples that should fail still fail in edition 2018.
* Prefer `rust,compile_fail` instead of `rust,ignore` ‒ the latter
allows the user to click on button and see the actual compile errors.
Also, this'll tell us if something stops failing.
