Stephane Eranian 6113af14c8 perf/x86: Add constraint for IVB CYCLE_ACTIVITY:CYCLES_LDM_PENDING 
The IvyBridge event CYCLE_ACTIVITY:CYCLES_LDM_PENDING can only
be measured on counters 0-3 when HT is off. When HT is on, you
only have counters 0-3.

If you program it on the eight counters for 1s on a 3GHz
IVB laptop running a noploop, you see:

           2 747 527 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
           2 747 527 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
           2 747 527 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
           2 747 527 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
       3 280 563 608 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
       3 280 563 608 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
       3 280 563 608 CYCLE_ACTIVITY:CYCLES_LDM_PENDING
       3 280 563 608 CYCLE_ACTIVITY:CYCLES_LDM_PENDING

Clearly the last 4 values are bogus.
