perf streams: Link stream pair
In previous patch, we have created an evsel_streams for one event, and top N hottest streams will be saved in a stream array in evsel_streams. This patch compares total streams among two evsel_streams. Once two streams are fully matched, they will be linked as a pair. From the pair, we can know which streams are matched.
