Get nashron work in opnjdk8

[Marcus Lagergren]

Can you tell us how you run it in JJS?

For the best current Nashorn performance, any build over Java8 b74 should be used, as it contains significant fixes to the inlining in the JVM.
You probably need to give any microbenchmark a few warmup rounds for performance to stabilize. If you only run one round, there will be too much noise and warmup issues for results to be meaningful. This is especially true with  invoke dynamic based programs running on Java 8 now, as they tend to warm up slower than standard "Java" programs.

Running with the octane test harness in the Nashorn repo (modified to provide multiple rounds for VM warmup)
(after doing ant externals to get the benchmarks) 

java -jar dist/nashorn.jar test/script/basic/run-octane.js -- test/script/external/octane/crypto.js --iterations 10 --verbose

I get ~2000 points on my machine, where Rhino gives me ~850 points.
