perf vendor events power8: Branch_prediction, latency, bus_stats, instruction_mix & instruction_stats metrics

POWER8 metrics are not well publicized.  Some are here:

  https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm

This patch is for metric groups:
- branch_prediction
- latency
- bus_stats
- instruction_mix
- instruction_stats_percent_per_ref
