Global stats are currently exposed using the legacy stat system (i.e., without a parent group). This change moves global stats from stat_control.cc to a group that gets exported from the Root object. The implementation adds the Root::Stats class which has a single global instance. This instance is exposed to the rest of the simulator using the global rootStats symbol. The intention is that objects that need global statistics in formulas access them through the rootStats object. The global names simSeconds, simTicks, simFreq, and hostSeconds are now references to their respective members in the rootStats object.
