Changes verbose mode to print both the table and the individual sample

8a84db909a Don't count a leading 1 as a signficant digit in the ratio.
What used to look like this:
            desk_pokemonwiki.skp    9.38ms -> 9.76ms    1x
                 tabl_pravda.skp     237us ->  241us    1x
          desk_css3gradients.skp     249us ->  254us    1x
            ....
               desk_fontwipe.skp    39.6us -> 38.7us    0.98x
                   tabl_digg.skp     922us ->  893us    0.97x
                  tabl_gmail.skp    20.7us ->   20us    0.96x

Now will print more like this:

            desk_pokemonwiki.skp    9.38ms -> 9.76ms    1.04x
                 tabl_pravda.skp     237us ->  241us    1.02x
          desk_css3gradients.skp     249us ->  254us    1.02x
            ....
               desk_fontwipe.skp    39.6us -> 38.7us    0.98x
                   tabl_digg.skp     922us ->  893us    0.97x
                  tabl_gmail.skp    20.7us ->   20us    0.96x

7ba39cb9a6 Add nanobench stats scripts to Skia repo.
These are the scripts I've been homegrowing for measuring perf impact.  I think we found them useful today as a way of sifting through the noise.
