Looks ok to me - I’ll integrate it.

The HSAIL Simulator does not support HSA group/local memory at this time, so if you run the tests with the JDK and the flag under the simulator, they will fail. Here I added "assumeTrue" to skip the test if running on the simulator which makes it easier for me to work with and test the Sumatra JDK.
