perf test: Add a test case for hists__{match,link}
As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.
