This removes the need for parsing stdout from the benchmarks. If the process wasn't executed by fork, it will just print like it used to. This also fixes the parsing of CLI arguments, by inferring the type from the options object instead of the value content. Only two benchmarks had to be changed: * http/http_server_for_chunky_client.js this previously used a spawn now it uses a fork and relays the messages using common.sendResult. * misc/v8-bench.js this utilized that v8/benchmark/run.js called global.print and reformatted the input. It now interfaces directly with the benchmark runner global.BenchmarkSuite.
