perf, x86: Add Intel SandyBridge CPU support
This patch adds basic SandyBridge support, including hardware
cache events and PEBS events support.
It has been tested on SandyBridge CPUs with perf stat and also
with PEBS based profiling - both work fine.
The patch does not affect other models.
v2 -> v3:
- fix PEBS event 0xd0 with right umask combinations
- move snb pebs constraint assignment to intel_pmu_init
v1 -> v2:
- add more raw and PEBS events constraints
- use offcore events for LLC-* cache events
- remove the call to Nehalem workaround enable_all function
