* benchmark/driver.rb: support memory usage benchmark.

  use `--measure-target=[target]'.
  Now, we can use the following targets:
    * real (default): real time which returns process time in sec.
    * peak: peak memory usage (physical memory) in bytes.
    * size: last memory usage (physical memory) in bytes.

* benchmark/memory_wrapper.rb: ditto.
