Hi all! Please review this PR to add a benchmark comparing the performance of Arrays.mismatch intrinsic in the JDK with that of the Vector API. Kindly refer to this [thread] on panama-dev regarding some initial discussion about this benchmark. I have attached the [results] of the full benchmark run along with the [assembly] output of a shorter run I had done while analysing the results. The benchmarks were run against the latest build of panama-vector available from builds.shipilev.net.
Also, I have not added the copyright header to this file yet as I am an individual contributor (OCA signed) and do not know what to put there.
