Multiple Performance Monitoring Run Statistics

There may be times when the number of events to be monitored exceed the number of counters. In
this case, multiple performance monitoring runs can be done, capturing different events from each
run. For example, the first run could monitor the events associated with instruction cache
performance and the second run could monitor the events associated with data cache performance.
By combining the results, statistics like total number of memory requests could be derived.
