Add "--log-cache-miss" option to generate a log of cache miss. (#241)

* Add "--log-cache-miss" option to generate a log of cache miss.

- This option must be used with "--ic" and/or "--dc" options
  to enable cache simulation.
- This option is useful with "-l" option to understand
  which instruction has caused the cache miss.

* Modify log format of cache miss to reduce log size.
