  [Clang] Show type in enum out of range diagnostic

  When the diagnostic for an out of range enum value is printed, it
  currently does not show the actual enum type in question, for example:

      v8/src/base/bit-field.h:43:29: error: integer value 7 is outside the valid range of values [0, 3] for this enumeration type [-Wenum-constexpr-conversion]
        static constexpr T kMax = static_cast<T>(kNumValues - 1);
                                  ^

  This can make it cumbersome to find the cause for the problem. Add the
  enum type to the diagnostic message, to make it easier.
