   // Try to label password fields and upload |form|. This differs from
   // OnFormSubmitted() in a few ways.
   //   - This function will only label the first <input type="password"> field
   //     as |password_type|. Other fields will stay unlabeled, as they
   //     should have been labeled during the upload for OnFormSubmitted().
   //   - This function does not assume that |form| is being uploaded during
   //     the same browsing session as it was originally submitted (as we may
   //     not have the necessary information to classify the form at that time)
   //     so it bypasses the cache and doesn't log the same quality UMA metrics.
