"block label not supported here" when the label is in the wrong place

[kpreid]

Code

fn main() {
    loop 'a: { return; }
}

Current output

error: block label not supported here
 --> src/main.rs:2:10
  |
2 |     loop 'a: { return; }
  |          ^^^ not supported here

Desired output

error: misplaced loop label
 --> src/main.rs:2:10
  |
2 |     loop 'a: { return; }
  |          ^^^ not supported here
  help: change this to `'a: loop {`
