Introduce a version of SunSpider that runs for a really long time (about 1 sec on my machine) Rubber stamped by Mark Hahnenberg. This isn't meant for serious VM-to-VM performance comparisons, but it is useful to see how these benchmarks behave when they're completely warmed up. * LongSpider: Added. * LongSpider/3d-cube.js: Added.
