  --runs            Number of times to run tests (default: $testRuns)
  --tests           Only run tests matching provided pattern
  --shark           Sample with the Mac OS X "Shark" performance testing tool (implies --runs=1)
  --shark20         Like --shark, but with a 20 microsecond sampling interval
  --shark-cache     Like --shark, but performs a L2 cache-miss sample instead of time sample
  --ubench          Use microbenchmark suite instead of regular tests (to check for core execution regressions)
  --v8              Use the V8 benchmark suite.
