Issue	Description
JDK-8130150	Implemented performance improvements for BigInteger.montgomeryMultiply We have implemented improvements that will improve performance of several security algorithms, especially when using ciphers with key lengths of 2048-bit or greater. To turn on these improvements, use the options -XX:+UseMontgomeryMultiplyIntrinsic and -XX:+UseMontgomerySquareIntrinsic. This improvement is only for Linux and Solaris on x86_64 architecture.
