This change isn't obvious to me. Maybe "// Thumbnails are only used on the webui
NTP, which isn't used on Android." (assuming that's the reason)?

We don't use instant_service.cc at on Android, but it is too hard to ifdef it
out. I will try to make a follow up CL trying to do that. For now, I'll add a
TODO(aurimas) to remove this ifdef.

       profile_, new FaviconSource(profile_, FaviconSource::FAVICON));

     content::URLDataSource::Add(
         profile_, new suggestions::SuggestionsSource(profile_));
   }
