The uncore PMU has a lot of duplicated PMUs for different subsystems.
When expanding an uncore alias we usually end up with a large
number of identically named aliases, which makes perf stat
output difficult to read.
Automatically sum them up in perf stat, unless --no-merge is s

It's the right default for uncore, and it doesn't do anything for
non uncore because these usually don't have duplicated event aliases
over different PMUs.
