Description
Create micro/nano-benchmark tests using JMH to verify there are no performance regressions compared to Unsafe and bytecode access.

Current JMH benchmarks are at:
  http://cr.openjdk.java.net/~shade/8080605/

The pre-built JAR can be executed with default settings, as "java -jar benchmarks.jar".
If you want to build the suite, then you need a VarHandles-enabled build (latest JDK 9 EA would probably suffice at some point)
