perf vendor events power8: Translaton & general 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:
- translation
- general

and other metrics not in a metric group.
