Previously we were dropping the useful longer descriptions that some
events have in the event list completely. This patch makes them appear with
perf list.
Old perf list:
baclears:
baclears.all
[Counts the number of baclears]
vs new:
perf list -v:
...
baclears:
baclears.all
[The BACLEARS event counts the number of times the front end is
resteered, mainly when the Branch Prediction Unit cannot provide
a correct prediction and this is corrected by the Branch Address
Calculator at the front end. The BACLEARS.ANY event counts the
number of baclears for any type of branch]
