perf metrics: Avoid segv if default metricgroup isn't set

commit e2b005d6ec0e738df584190e21d2c7ada37266a0 upstream.

A metric is default by having "Default" within its groups. The default
metricgroup name needn't be set and this can result in segv in
default_metricgroup_cmp and perf_stat__print_shadow_stats_metricgroup
that assume it has a value when there is a Default metric group. To
avoid the segv initialize the value to "".

perf metrics: Sort the Default metricgroup

The new default mode will print the metrics as a metric group. The
metrics from the same metric group must be adjacent to each other in the
metric list. But the metric_list_cmp() sorts metrics by the number of
events.

Add a new sort for the Default metricgroup, which sorts by
default_metricgroup_name and metric_name.

Add is_default in the struct metric_event to indicate that it's from
the Default metricgroup.

Store the displayed metricgroup name of the Default metricgroup into
the metric expr for output.

Introduce a new metricgroup, Default, to tag all the metric groups which

Add a new field, DefaultMetricgroupName, in the JSON file to indicate
the real metric group name. It will be printed in the default output
to replace the event names.

There is nothing changed for the output format.

On SPR, both TopdownL1 and TopdownL2 are displayed in the default
output.

On ARM, Intel ICL and later platforms (before SPR), only TopdownL1 is
displayed in the default output.

Ids/events from a metric are turned into an event string and parsed;
setup_metric_events matches the id back to the parsed evsel. With
hybrid the same event may exist on both PMUs with the same name and be
being used by metrics at the same time. A metric on cpu_core therefore
shouldn't match against evsels on cpu_atom, or the metric will compute
the wrong value. Make the matching sensitive to the PMU being parsed.

perf metric: JSON flag to not group events if gathering a metric group

Some metric groups have metrics that don't have fully overlapping
events, meaning that the group's events become unique event groups that
may need to multiplex with each other. This can be particularly
unfortunate when the groups wouldn't need to multiplex because there are
sufficient hardware counters.

Add a flag so that if recording a metric group then the metrics within
the group needn't use groups for their events. The flag is added to
Intel TopdownL1 and TopdownL2 metrics.

Do defensive programming by using zfree() to initialize freed pointers

instead of more subtle behaviour.

This file already used zfree() in other places, so this just plugs some

perf stat: Implement --topdown using json metrics

Request the topdown metric group of a level with the metrics in the
group 'TopdownL<level>' rather than through specific events. As more
topdown levels are supported this way, such as 6 on Intel Ice Lake,
default to just showing the level 1 metrics. This can be overridden
using '--td-level'. Rather than determine the maximum topdown level
from sysfs, use the metric group names. Remove some now unused topdown
code.

When there are no events and on Intel, the topdown events will be

these request special handling in stat-shadow.c. To more easily update
these metrics use the json metric version via the TopdownL1
group. This makes the handling less platform specific.

Rename metric_constraint to event_grouping to better explain what the
variable is used for. Switch to use an enum for encoding instead of a
string. Rather than just no constraint/grouping information or
"NO_NMI_WATCHDOG", have 4 enum values. The values encode whether to
group or not, and two cases where the behavior is dependent on either
the NMI watchdog being enabled or SMT being enabled.
