Summary JSC should have a way to gather and log Heap memory use and pause times

In order to improve our infrastructure for benchmark-driven development, we should have a centralized method of gathering and logging various statistics about the state of the JS heap. This would allow us to create and to use other tools to analyze the output of the VM after running various workloads. The first two statistics that might be interesting is memory use by JSC and GC pause times. We can control whether this recording happens through the use of the Options class, allowing us to either use environment variables or command line flags.
