go/types: tweaks to ArgumentError to be more idiomatic This CL makes a few changes to the new ArgumentError type to be more idiomatic: - Use a pointer receiver for methods. - Export fields, similarly to Error. ArgumentError has a clear meaning (an error associated with an index), so there is no need to hide its representation. - Add an Unwrap method to access the underlying error. - Say explicitly that the error returned from Instantiate may wrap *ArgumentError. There is no need to commit to an API that always returns an error with dynamic type *ArgumentError.
