Subject: [PATCH 01/26] perf tools: Factor output_resort from hists__output_resort

Current hists__output_resort depends on hists based on
hists_evsel struct, but we need to be able to sort common
hists as well.

Cutting out the sorting base sorting code into output_resort
function, so it can be reused in following patch.
