Review request for JDK-8060242

[Attila Szegedi]

Please review JDK-8060242 at <http://cr.openjdk.java.net/~attila/8060242/webrev.00> for <https://bugs.openjdk.java.net/browse/JDK-8060242>

The fix is mostly in the TypeEvaluator.java, the rest is just plumbing (ArrayBufferView has to be public so I can us it with instanceof; array data subclasses for buffer views need to support optimistic operations; Int/Long/Number/ObjectArrayData now inherit they getOptimisticType() from ContinuousArrayData; finally there was a genuine data type bug where NativeUint32Array reported its array element type to be int instead of long).

Thanks,
  Attila.
