I guess this does not have to be called on the UI thread, but can be called on
any thread. So this should be fine.

Looking at field_trial.h it says that it should only be called on the UI thread,
though I see locks and no thread checks in the implementation. Should the
comment be updated? Adding jar@

   if (StartsWithASCII(experiment, "ExperimentYes", false))
     return true;
