[jdk13u-dev] RFR: 8243114: Implement montgomery{Multiply, Square}intrinsics on Windows

Fri Dec 11 08:59:02 UTC 2020

I'd like to backport 8243114 to 13u for parity with 11u.
The patch doesn't apply cleanly due to minor context difference in stubGenerator_x86_64.cpp, reapplied manually.
Tested with tier1 and jdk_security with additional options -XX:+UseMontgomeryMultiplyIntrinsic -XX:+UseMontgomerySquareIntrinsic.
