Track where diagnostics were created. This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`. For example, the following code... ```rust struct A; struct B; fn main(){ let _: A = B; } ``` ...now emits the following error message: ``` error[E0308]: mismatched types --> src\main.rs:5:16 | 5 | let _: A = B; | - ^ expected struct `A`, found struct `B` | | | expected due to this -Ztrack-diagnostics: created at compiler\rustc_infer\src\infer\error_reporting\mod.rs:2275:31 ``` |
