Page 3135, Table 19-2. Non-Architectural Performance Events In the
Processor Core of Third Generation Intel Core i7, i5, i3 Processors

(aka. IvyBridge)

B1H 01H UOPS_EXECUTED.THREAD Counts total number of uops to be
                             executed per-thread each cycle. Set
                             Cmask = 1, INV =1 to count stall
                             cycles.
