Esteban Küber d68f2a6b71 Mention when type parameter could be Clone 
```
error[E0382]: use of moved value: `t`

The `help` is new. On ADTs, we also extend the output with span labels:

```
error[E0507]: cannot move out of static item `FOO`
  --> $DIR/issue-17718-static-move.rs:6:14

LL |     let _a = FOO;

note: if `Foo` implemented `Clone`, you could clone the value

   |
