[jdk21u-dev] RFR: 8316592: RISC-V: implement poly1305 intrinsic

Wed Dec 20 14:19:57 UTC 2023

Backport for `_poly1305_processBlocks` intrinsic. Review here: https://github.com/openjdk/jdk/pull/16417. I re-run the tier1 tests and `test/jdk/com/sun/crypto/provider/Cipher/ChaCha20/unittest/Poly1305UnitTestDriver.java` test specifically just as a sanity checks and they're ok.
