Optimized x86 intrinsics for unsigned division and modulus operations are already implemented in ~~JDK-8282221~~. They can be further optimized for the special case of division by constants and powers of 2 but this is not yet implemented in ~~JDK-8282221~~. The goal of this enhancement is to implement the above mentioned optimization.
