I created the following patch for the IBM Power 7 and Power 7+ systems.
Please review and if acceptable commit it to the perfmon 2 source code
tree. Thank you.

Power 7, change the code for the PM_RUN_INST_CMPL and PM_RUN_CYC events
The Power 7 processor has four programmable counters and two fixed counters.
Currently, the codes returned for PM_RUN_INST_CMPL and PM_RUN_CYC are for
the programmable counters. This patch changes the returned code to the
fixed counter code thus freeing up the programmable counters for other
events.
