[vector] Replace IllegalArgumentE with UnsupportedOE for zero arg methods

[Viswanathan, Sandhya]

Hi Paul,

Changes look good. Only one question below:

For ByteVector.java and ShortVector.java, the method viewAsFloatingLanes is throwing AssertionError and not UnsupportedOperationException:

     viewAsFloatingLanes() {
         LaneType flt = LaneType.SHORT.asFloating();
         throw new AssertionError();  // should already throw IAE
     }

Best Regards,
Sandhya

Hi,

Please review the following change replacing IllegalArgumentException with UnsupportedOperationException for some methods that accept zero args:

This change is in response to reviews in preparation for integration into jdk/jdk.
