For matching and/or linking hist entries, they need to be sorted by given sort keys. However current hists__match/link did this on the output trees, so that the entries in the output tree need to be resort before doing it. This looks not so good since we have trees for collecting or collapsing entries before passing them to an output tree and they're already sorted by the given sort keys. Since we don't need to print anything at the time of matching/linking, we can use these internal trees directly instead of bothering with double resort on the output tree. Its only user - at the time of this writing - perf diff can be easily converted to use the internal tree and can save some lines too by getting rid of unnecessary resorting codes.
