> This implement SHA-384/SHA-512 transformation using aarch64 v8.2
> SHA512 Crypto Extensions.
> Reference implementation:
> We used QEMU system emulator which supports SHA512 instructions to
> test the functionality.
> SHA512 basic functionality is tested with:
> Patch passed jtreg tier1-3 test with QEMU system emulator.
> We've also verified it with full jtreg tests without SHA512 instructions on
> aarch64-linux-gnu, to make sure that there's no regression.
> We've also created a JMH for performance test:
> We measured the performance benefit with a cycle-accurate simulator.
> Patch delivers more than 2x performance gain measured with the three
> different size message.
