2c56ba5cde Don't suppress nanobench output table in verbose mode 
Changes verbose mode to print both the table and the individual sample
values. No need to hold back information in verbose mode.

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.
