cpu: o3: remove stat totalCommittedInsts

This patch removes the stat totalCommittedInsts.  This variable was used for
recording the total number of instructions committed across all the threads
of a core.  The instructions committed by each thread are recorded invidually.
The total would now be generated by summing these individual counts.
