Implements verification of
- Bits of ESCR EventMask field (meaningful bits in field are hardware
predefined and others bits should be set to zero)
- INSTR_COMPLETED event (it is available on predefined cpu model only)
- Thread shared events (they should be guarded by "perf_event_paranoid"
sysctl due to security reason). The side effect of this action is
that PERF_COUNT_HW_BUS_CYCLES become a "paranoid" general event.
