perf stat: Add extra output of counter values with -vv
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
