Since you already have IR tests in place we can follow up with a proper set of unit tests operating over long arrays like we do for boolean and with various mask operations. If you log the follow up issue i might be able to find someone else to write those tests.

Sounds reasonable to me @PaulSandoz ! I will revert the smoke tests in next commit. And I'v filed another JBS as a follow-up for the unit tests: https://bugs.openjdk.org/browse/JDK-8371446. Thanks a lot!
