`break` inside async closure has incorrect span for enclosing closure

[dtolnay]

Code

#![feature(async_closure)]

fn main() {
    let _ = || break;
    let _ = async || break;
}

Current output

error[E0267]: `break` inside of a closure
 --> src/main.rs:4:16
  |
4 |     let _ = || break;
  |             -- ^^^^^ cannot `break` inside of a closure
  |             |
  |             enclosing closure

error[E0267]: `break` inside of a closure
 --> src/main.rs:5:22

5 |     let _ = async || break;
  |                      ^^^^^
  |                      |
  |                      cannot `break` inside of a closure
  |                      enclosing closure

Desired output

...

error[E0267]: `break` inside of a closure
 --> src/main.rs:5:13
  |
5 |     let _ = async || break;
  |             -------- ^^^^^
