PTAL. The test tryjob runs with extra flags.

Hmm - hold on - something's not right yet...

[Michael Achenbach, 2015-09-18 07:31:13]

PTAL - everything was right - I just ran into a pitfall - now I ran these jobs
successfully:

tools/try_perf.py --linux64 sunspider --extra-flags "--predictable --turbo"
tools/try_perf.py --linux64 sunspider "--extra-flags=--prof --predictable"
tools/try_perf.py --linux64 sunspider --extra-flags=--prof

Pitfall:
tools/try_perf.py --linux64 sunspider --extra-flags="--predictable --turbo"
