nit: Please write this more like how it was previously written:

if (!creditcard_field_value.empty() &&
    (StartsWith(creditcard_field_value, field_contents, false) ||
     (type.GetStorableType() == CREDIT_CARD_NUMBER &&
      base::string16::npos != creditcard_field_value.find(field_contents))))

Done.

       // If the value is the card number, the label is the expiration date.
       // Otherwise the label is the card number, or if that is empty the
       // cardholder name. The label should never repeat the value.
       base::string16 label;
