During a recent crater run, we ran into a few circumstances where cargo fix failed unexpectedly, and we can't reproduce the errors locally. The sequence was:

  1. Cargo ran rustc and collected the diagnostics to apply, and modified the files.
  2. Cargo ran rustc again to verify the fixes. This step failed, but only emitted warnings.
  3. Cargo ran rustc again to show the original diagnostics, and this exited normally with warnings.

We don't know why the second step failed. This change makes it so that cargo will collect any non-diagnostic messages (like ICEs), and will also display the exit code if it is abnormal.

I'm hoping to have this for the next crater run to diagnose the unexpected errors.
