perf vendor events: Update metrics for Ivybridge 

Based on TMA_metrics-full.csv version 4.3 at 01.org:
    https://download.01.org/perfmon/
Events are still at version 21:
    https://download.01.org/perfmon/IVB
Json files generated by:

Tested:

  ...
    6: Parse event definition strings                                  : Ok
    7: Simple expression parser                                        : Ok
  ...
    9: Parse perf pmu format                                           : Ok
   10: PMU events                                                      :
   10.1: PMU event table sanity                                        : Ok
   10.2: PMU event map aliases                                         : Ok
   10.3: Parsing of PMU event table metrics                            : Ok
   10.4: Parsing of PMU event table metrics with fake PMUs             : Ok
  ...
   68: Parse and process metrics                                       : Ok
  ...
   88: perf stat metrics (shadow stat) test                            : Ok
   89: perf all metricgroups test                                      : Ok
   90: perf all metrics test                                           : FAILED!
   91: perf all PMU test                                               : Ok
  ...

Test 90 failed for Load_Miss_Real_Latency with <not counted> events:

 Performance counter stats for 'perf bench internals synthesize':

     <not counted>      mem_load_uops_retired.hit_lfb                                     (0.00%)
     <not counted>      MEM_LOAD_UOPS_RETIRED.L1_MISS                                     (0.00%)
     <not counted>      L1D_PEND_MISS.PENDING                                         (0.00%)
         558185217 ns   duration_time

This is exposing a somewhat known issue with weak groups that can
be worked around with:

$ perf stat --metric-no-group -M Load_Miss_Real_Latency -a sleep 1

 Performance counter stats for 'system wide':

          14935022      mem_load_uops_retired.hit_lfb #    23.55 Load_Miss_Real_Latency   (83.23%)
           4716714      MEM_LOAD_UOPS_RETIRED.L1_MISS                                     (66.68%)
         462705675      L1D_PEND_MISS.PENDING                                         (83.22%)
