[PATCH 10/10] perf, tools, stat: Add extra output of counter values with -vv

[Andi Kleen]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Add debug output of raw counter values per CPU when
perf stat -v is specified, together with their cpu numbers.
This is very useful to debug problems with per core counters,
where we can normally only see aggregated values.

v2: Make it depend on -vv, not -v
