  Log:
    * benchmark/bm_vm3_thread_mutex.rb: remove it.
    * benchmark/bm_vm3_thread_mutex[1-3].rb: added 3 benchmarks.
      1: one thread with one mutex (no contention).
      2: two threads with one mutex (contention).
      3: 1000 threads with one mutex (huge number of contention)
      Abobe removed benchmark was type 3.
      Therefore, this commit adds type 1 and 2 benchmark.
