E0062 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0062.rs

Error E0062 needs a span_label, updating it from:

error[E0062]: field `x` specified more than once
  --> src/test/compile-fail/E0062.rs:18:9
   |
18 |         x: 0, //~ ERROR E0062
   |         ^

To:

error[E0062]: field `x` specified more than once
  --> src/test/compile-fail/E0062.rs:18:9
   |
18 |         x: 0, //~ ERROR E0062
   |         ^ used more than once

Bonus: we should also include the span_label for the first time it was used as a secondary label.
