Esteban Küber 9f730e92f2 Suggest setting lifetime in borrowck error involving types with elided lifetimes 
```
error: lifetime may not live long enough
  --> $DIR/ex3-both-anon-regions-both-are-structs-2.rs:7:5
   |
LL | fn foo(mut x: Ref, y: Ref) {
   |        -----       - has type `Ref<'_, '1>`
   |        |
   |        has type `Ref<'_, '2>`
LL |     x.b = y.b;
   |     ^^^^^^^^^ assignment requires that `'1` must outlive `'2`
   |
help: consider introducing a named lifetime parameter
   |
LL | fn foo<'a>(mut x: Ref<'a, 'a>, y: Ref<'a, 'a>) {
   |       ++++           ++++++++        ++++++++
```

As can be seen above, it currently doesn't try to compare the `ty::Ty` lifetimes that diverged vs the `hir::Ty` to correctly suggest the following

```

   |
LL | fn foo<'a>(mut x: Ref<'_, 'a>, y: Ref<'_, 'a>) {
   |       ++++           ++++++++        ++++++++
```

but I believe this to still be an improvement over the status quo.
