Namely, use a more sensical primary span. Don't pretty-print AST nodes for the diagnostic message. Why: * It's lossy (e.g., it doesn't replicate trailing `+`s in trait objects. * It's prone to leak error nodes (printed as `(/*ERROR*/)`) since the LHS can easily represent recovered code (e.g., `fn(i32?) + T`).
