    Description

      multiplyHigh has been added to java.langMath and its intrinsic implemented, but an unsigned version is more useful for crypto algorithms. While one can fairly easily be calculated from the other, it is slightly slower to make the adjustment and it makes sense to have methods and intrinsics for both.
