make tests output spin on the same line by default

Make tests output spin on the same line by default.

-v now gives a cleaned-up version of the existing output (every test timed, useless information removed)

Example output, default:
  [ 36/193] PathOpsCubicIntersectionOneOffTest
then later when finished...
  [193/193] BlurMaskFilter

Example output, -v:  (note, codereview is messing up my pretty spacing)

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
