Return `true` if this object represents an empty string value, and `false` otherwise. This object represents an empty string value if `begin() == end()`. Note that this method is functionally identical with the `isEmpty` method and allows developers to avoid distracting syntax differences when `StringRef` appears in juxtaposition with `string`, which defines `empty` but not `isEmpty`.
