perf: Fix LLC-* events on Intel Nehalem/Westmere
On Intel Nehalem and Westmere CPUs the generic perf LLC-* events count the
L2 caches, not the real L3 LLC - this was inconsistent with behavior on
other CPUs.
Fixing this requires the use of the special OFFCORE_RESPONSE
events which need a separate mask register.
This has been implemented by the previous patch, now use this infrastructure
to set correct events for the LLC-* on Nehalem and Westmere.
