ruby: tag and data cache access support

Updates to Ruby to support statistics counting of cache accesses.  This feature
serves multiple purposes beyond simple stats collection.  It provides the
foundation for ruby to model the cache tag and data arrays as physical
resources, as well as provide the necessary input data for McPAT power
modeling.
