New Metrics:
- DSB_Switches: fraction of cycles CPU was stalled due to switches from DSB to MITE pipeline [all]
- L2_Evictions_{Silent|NonSilent}_PKI: L2 {silent|non silent} ecivtions rate per Kilo instruction [SKX+]
- IpFarBranch - Instructions per Far Branch
Other Enhancements & fixes:
- KBLR/CFL & CLX move to separate columns (no column sharing via if #model)
- Re-organized/renamed Metric Group

Update all the Intel JSON metrics from Ahmad Yasin's TMAM 3.5
for Intel big core from Sandy Bridge to Cascade Lake.
This has many improvements and new metircs
- New TopDownL1_SMT group that provides a per SMT thread version
of --topdown that does not require -a anymore. The drawback is
increased multiplexing though since L1 TopDown does not fit into
4 generic counters anymore.
- Added SMT aware versions of other metrics
- Split SMT aware metrics into separate metrics to avoid
unnecessary event collections
- New metrics for better branch analysis:
Estimated Branch_Mispredict_Costs, Instructions per taken Branch,
Branch Instructions per Taken Branch, etc.
- Instruction mix metrics:
Instructions per load, Instructions per store, Instructions per Branch,
Instructions per Call
- New Cache metrics:
Bandwidth to L1/L2/L3 caches. L1/L2/L3 misses per kilo instructions.
memory level parallelism
- New memory controller metrics:
Normalized memory bandwidth in interval mode, Average memory latency,
Average number of parallel read requests,
- 3DXP persistent memory metrics for Cascade Lake:
3dxp read latency, 3dxp read/write bandwidth
- Some other useful metrics like Instruction Level Parallelism,
- Various other improvements.
Not all metrics are available on all CPUs. Skylake has best coverage.

Go over the tools/ files that are maintained in Arnaldo's tree and
fix common typos: half of them were in comments, the other half
in JSON files.
( Care should be taken not to re-import these typos in the future,
if the JSON files get updated by the vendor without fixing the typos. )
No change in functionality intended.
Committer notes:
This was split from a larger patch as there are code that is,
additionally, maintained outside the kernel tree, so to ease cherry
picking and/or backporting, split this into multiple patches.

Some of the metrics use an incorrect syntax for specifying the cmask for
an event. Convert to perf syntax so that they can be resolved.
Fixes metrics on Broadwell, SandyBridge.
