suggestion: Igor made --turbo imply --crankshaft, to make these two flags stay
in sync we should make --turbo imply --opt as well. WDYT?

that would mean that if we set --turbo via finch, --noopt wouldn't work anymore

     const char* filter_flag = "--turbo-filter=*";
     FlagList::SetFlagsFromString(filter_flag, StrLength(filter_flag));
   }
