Suggest using `as_ref` on some borrow errors [hack]
When encountering the following code:
```rust
struct Foo;
fn takes_ref(_: &Foo) {}
let ref opt = Some(Foo);
opt.map(|arg| takes_ref(arg));
```
Suggest using `opt.as_ref().map(|arg| takes_ref(arg));` instead.
This is a stop gap solution until we expand typeck to deal with these
cases in a more graceful way.
