Performance test of the jsc with POC, without POC, and without Arrow function

Collected 4 samples per benchmark/VM, with 4 VM invocations per benchmark. Ran 10 benchmark iterations, and measured the
total time of those iterations, for each sample. Emitted a call to gc() between sample measurements. Used 50 benchmark
iterations per VM invocation for warm-up. Used the jsc-specific preciseTime() function to get microsecond-level timing.
Reporting benchmark execution times with 95% confidence intervals in milliseconds.
