- Add a `HandleCycleError` enum to rustc_query_system, along with a `handle_cycle_error` function - Move `Value` to rustc_query_system, so `handle_cycle_error` can use it - Move the `Value` impls from rustc_query_impl to rustc_middle. This is necessary due to orphan rules.
For more information about how the query system works, see the rustc dev guide.
