I'm not too happy with how span-based this approach is. I think this is generally a shortcoming of trait selection errors, given the way that we fail to track much of the necessary "source" information. But I guess it's not significantly worse than existing diagnostics code. @bors r+ rollup |

span_look_ahead is not correct sometimes, can we use the expr way to find out there is a method call?

I originally tried to do that, but couldn't get a expr of the actual method call. When I tried using FindExprBySpan, it returned None.
