When encountering a moved value of a type that isn't `Clone` because of unmet obligations, but where all the unmet predicates reference crate-local types, mention them and suggest cloning, as we do in other cases already:
```
error[E0507]: cannot move out of `foo`, a captured variable in an `Fn` closure
--> f111.rs:14:25
|
13 | fn do_stuff(foo: Option<Foo>) {
| --- captured outer variable
14 | require_fn_trait(|| async {
| -- ^^^^^ `foo` is moved here
| |
| captured by this `Fn` closure
15 | if foo.map_or(false, |f| f.foo()) {
| ---
| |
| variable moved due to use in coroutine
| move occurs because `foo` has type `Option<Foo>`, which does not implement the `Copy` trait
|
note: if `Foo` implemented `Clone`, you could clone the value
--> f111.rs:4:1
|
4 | struct Foo;
| ^^^^^^^^^^ consider implementing `Clone` for this type
...
15 | if foo.map_or(false, |f| f.foo()) {
| --- you could clone this value
