perf evlist: Maintain evlist->all_cpus
Maintain a cpumap in the evlist that is the union of all the cpus of the
events.
This needs a cpumap merge operation, which is added together with tests.
v2:
Add tests for cpu map merge
Fix handling of duplicates
Rename _update to _merge
Factor out sorting.
Fix handling of NULL maps in merge
v3:
Add comments and empty lines to _merge
Committer testing:
# perf test "Merge cpu map"
52: Merge cpu map : Ok
