[vector] RFR 8219878: Vectorized Poly1305 benchmark

[Viswanathan, Sandhya]

Hi Adam,

Thanks. Do you need help pushing the Poly1305 benchmark to vectorIntrinsics? 

Best Regards,
Sandhya

On a Core i7-4980HQ (Haswell) at 2.8 GHz:

Scalar Poly1305 (JDK 11): 600 MB/s
This benchmark without the optimization: 800 MB/s
This benchmark with the optimization: 2200 MB/s
