perf test: Add round trip test for sw and hw event names
It basically traverses the hardware and software event name arrays
creating an evlist with all events, then it uses perf_evsel__name to
check that the name is the expected one.
With it I noticed this problem:
[root@sandy ~]# perf test 10
10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations'
Run 'perf list' for a list of valid events
FAILED!
Changed it to "cpu-migrations" in the software event arrays and it
worked.
This is to catch problems like the one reported by Joel Uckelman in
http://permalink.gmane.org/gmane.linux.kernel.perf.user/1016
Hardware cache events will be checked in the following patch.
