Andi Kleen 6c5f4e5cb3 perf stat: Don't merge events in the same PMU 
Event merging is mainly to collapse similar events in lots of different
duplicated PMUs.

It can break metric displaying. It's possible for two metrics to have
the same event, and when the two events happen in a row the second
wouldn't be displayed.  This would also not show the second metric.

To avoid this don't merge events in the same PMU. This makes sense, if
we have multiple events in the same PMU there is likely some reason for
it (e.g. using multiple groups) and we better not merge them.

While in theory it would be possible to construct metrics that have
events with the same name in different PMU no current metrics have this
problem.

This is the fix for perf stat -M UPI,IPC (needs also another bug fix to
completely work)
