[V3 PATCH] perf parse-events: Specially handle uncore event alias in small groups

From: Kan Liang Perf stat doesn't count the uncore event aliases from the same uncore block in a group, for example: perf stat -e '{unc_m_cas_count.all,unc_m_clockticks}' -a -I 1000 # time counts unit events 1.000447342unc_m_cas_count.all 1.000
