Description
Need to disable new intrinsics introduced by JDK-8130150 and JDK-8081778 by default. They will remain enableable with proper flags. To enable the new intrinsics - one would need to launch VM with these flags in JDK 8u releases : -XX:+UseMontgomerySquareIntrinsic -XX:+UseMontgomeryMultiplyIntrinsic -XX:+UseSquareToLenIntrinsic -XX:+UseMultiplyToLenIntrinsic
