this change makes it so that the renderer no longer decides to swap processes
for a redirect. it's now decided by the browser.

       command_line.HasSwitch(switches::kEnableStrictSiteIsolation)) {
     GURL referrer(request.httpHeaderField(WebString::fromUTF8("Referer")));
     OpenURL(frame, url, referrer, default_policy);
