The solution is to put this on two lines:

name = NameToFunctionName(name);
set_name(*name);

   return isolate->heap()->undefined_value();
 }
 
 
 RUNTIME_FUNCTION(Runtime_FunctionNameShouldPrintAsAnonymous) {
   SealHandleScope shs(isolate);
   DCHECK(args.length() == 1);
   CONVERT_ARG_CHECKED(JSFunction, f, 0);
   return isolate->heap()->ToBoolean(
       f->shared()->name_should_print_as_anonymous());
