Looks good to me on a first pass, but given that this touches r? @oli-obk |

The other changes seem fine to me. I will be refactoring them in the future anyway, so cleaning up the API for them a bit just makes my job easier ^^ |

We have several methods indicating the presence of errors, lint errors, and delayed bugs. I find it frustrating that it's very unclear which one you should use in any particular spot. This commit attempts to instill a basic principle of "use the least general one possible", because that reflects reality in practice -- `has_errors` is the least general one and has by far the most uses (esp. via `abort_if_errors`). Specifics: - Add some comments giving some usage guidelines. - Prefer `has_errors` to comparing `err_count` to zero. - Remove `has_errors_or_span_delayed_bugs` because it's a weird one: in the cases where we need to count delayed bugs, we should really be counting lint errors as well. - Rename `is_compilation_going_to_fail` as `has_errors_or_lint_errors_or_span_delayed_bugs`, for consistency with `has_errors` and `has_errors_or_lint_errors`. - Change a few other `has_errors_or_lint_errors` calls to `has_errors`, as per the "least general" principle. This didn't turn out to be as neat as I hoped when I started, but I think it's still an improvement.
