ruby: stats: use gem5's stats for cache and memory controllers
This moves event and transition count statistics for cache controllers to gem5's statistics. It does the same for the statistics associated with the memory controller in ruby. All the cache/directory/dma controllers individually collect the event and transition counts. A callback function, collateStats(), has been added that is invoked on the controller version 0 of each controller class. This function adds all the individual controller statistics to a vector variables. All the code for registering the statistical variables and collating them is generated by SLICC. The patch removes the files *_Profiler.{cc,hh} and *_ProfileDumper.{cc,hh} which were earlier used for collecting and dumping statistics respectively.
