ruby: replace Time with Tick in replacement policy classes

Testing Done

How come this is in Ticks, and the other patches replace Time with Cycles?

Because the CacheMemory class is not a clocked object, but makes calls to
these functions in the replacement policy classes.

Would it be an option to make it a ClockedObject (or is that overkill)?

You have a pending review.
