[PATCH v2 00/22] Improvements to Intel perf metrics

[Ian Rogers <irogers@google.com>]

For consistency with:
https://github.com/intel/perfmon-metrics
rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.

Remove _SMT suffix metrics are dropped as the #SMT_On and #EBS_Mode
are correctly expanded in the single main metric. Fix perf expr to
allow a double if to be correctly processed.

Add all 6 levels of TMA metrics. Child metrics are placed in a group
named after their parent allowing children of a metric to be
easily measured using the metric name with a _group suffix.

Don't drop TMA metrics if they contain topdown events.

The ## and ##? operators are correctly expanded.

The locate-with column is added to the long description describing a
sampling event.

Metrics are written in terms of other metrics to reduce the expression
size and increase readability.

Following this the pmu-events/arch/x86 directories match those created
by the script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf

v2. Fixes commit message wrt missing mapfile.csv updates as noted by
    Zhengjun Xing <zhengjun.xing@linux.intel.com>. ScaleUnit is added
    for TMA metrics. Metrics with topdown events have have a missing
    slots event added if necessary. The latest metrics at:
    https://github.com/intel/perfmon-metrics are used, however, the
    event-converter-for-linux-perf scripts now prefer their own
    metrics in case of mismatched units when a metric is written in
    terms of another.  Additional testing was performed on broadwell,
    broadwellde, cascadelakex, haswellx, sapphirerapids and tigerlake
    CPUs.
