perf vendor events intel: Update ivytown TMA metrics to 4.7
Top-Down Microarchitecture Analysis (TMA) metrics simplify
cycle-accounting using microarchitecture-abstracted metrics
organized in one hierarchy. This update is from version 4.5 to
4.7.
The update includes:
- Swapped tma_info_core_ilp (becomes per SMT thread) and
tma_info_pipeline_execute (per physical core).
- Reduced number of events when SMT is off.
- Tuned thresholds for tma_fetch_bandwidth and
tma_ports_utilized_3m.
The update came from:
https://github.com/intel/perfmon/pull/140
https://github.com/intel/perfmon/pull/138
