perf tests attr: Add optional term

2017-07-19T02:14:22+00:00

Some of the stat events are quite rare to find on common machines (like
front end cycles).

Adding an 'optional' term to mark such events in attr tests. Event
marked as optional will not fail the test case if it's not found in
results.

perf tests attr: Fix precise_ip setup

2017-07-19T02:14:21+00:00

We have a test to detect to highest precise possible, so test can't just
predict precise_ip value.

perf tests attr: Fix sample_period setup

2017-07-19T02:14:20+00:00

The final period can differ from what user specifies on command line due
to the perf_event_max_sample_rate sysctl setup.

Thus we can't predixt the sample_period value any more.

2017-07-19T02:14:19+00:00

The stat command creates all events disabled and enables them either
manualy or via the enable_on_exec bit.

perf tests attr: Add proper return values

2017-07-19T02:14:19+00:00

The record command now properly returns the status of the tracee if
there's any. We need to properly set the expected return value of the
tracee in the attr tests.

perf tests attr: Add 1s for exclude_kernel and task base bits

2017-07-19T02:14:17+00:00

There's an event open fallback which set exclude_kernel=1 in case use
does not have enough privileges. Adding both 0|1 for this attribute,
because we don't know what value it is.
