perf parse-events: Wildcard legacy cache events
It is inconsistent that "perf stat -e instructions-retired" wildcard
opens on all PMUs while legacy cache events like "perf stat -e
L1-dcache-load-miss" do not. A behavior introduced by hybrid is that a
legacy cache event like L1-dcache-load-miss should wildcard open on
all hybrid PMUs. Previously hybrid would call to is_event_supported
for each PMU, a failure of which results in the event not being
added. This isn't done in this case as the parser should just create
perf_event_attr and the later open should fail, or the counter give
"<not counted>". If this wants to be avoided then the PMU can be named
with the event.
