The metric code uses the event parsing code but it generally assumes
all events are supported. Arnaldo reported AMD supporting
stalled-cycles-frontend but not stalled-cycles-backend [1]. An issue
with this is that before parsing happens the metric code tries to
share events within groups to reduce the number of events and
multiplexing. If the group has some supported and not supported
events, the whole group will become broken. To avoid this situation
add has_event tests to the metrics for stalled-cycles-frontend and
stalled-cycles-backend. has_events is evaluated when parsing the
metric and its result constant propagated (with if-elses) to reduce
the number of events. This means when the metric code considers
sharing the events, only supported events will be shared.
Note for backporting. This change updates
tools/perf/pmu-events/empty-pmu-events.c a convenience file for builds
on systems without python present. While the metrics.json code should
backport easily there can be conflicts on empty-pmu-events.c. In this
case the build will have left a file test-empty-pmu-events.c that can
be copied over empty-pmu-events.c to resolve issues and make an
appropriate empty-pmu-events.c for the json in the source tree at the
time of the build.

These events are never countable by the PMU and are only intended to
be used as external inputs to trace. Therefore showing them in 'perf
list' is misleading so remove them.
The generator script doesn't emit these events when used with the new
telemetry-solution input files [1].
'perf list' should only show countable events because there are events
that are sometimes implemented, sometimes countable and sometimes not,
for example TRB_TRIG. If we always include any implemented events
whether they are countable or not then it's not possible to tell whether
they are usable in perf without going to the docs, defeating the point
of 'perf list'.
It's also not useful yet to display implemented events that are not
countable (for help in using trace rather than perf stat), because
PMU_OVFS and PMU_HOVFS are practically always implemented and TRB_TRIG
is always implemented when there is TRBE.

The legacy-hardware.json is added containing hardware events similarly
to the software.json file. A difference is that for the software PMU
the name is known and matches sysfs. In the legacy-hardware.json no
Unit/PMU is specified for the events meaning default_core is used and
the events will appear for all core PMUs.
There are potentially 1216 legacy cache events, rather than list them
in a json file add a make_legacy_cache.py helper to generate them.
By using json for legacy hardware and cache events: descriptions of
the events can be added; events can be marked as deprecated, such as
those misleadingly named l2 (deprecated is also used to mark all
events that weren't previously displayed in perf list); and the name
lookup becomes case insensitive.
The C string encoding all the perf events and metrics is increased in
size by 123,499 bytes which will increase the perf binary size. Later
changes will remove hard coded event parsing for legacy hardware and
cache events, turning parsing overhead into a binary search during
event lookup.
That event descriptions are based off of those in perf_event_open man
page, credit to Vince Weaver <vincent.weaver@maine.edu>.
