Hm, how about a separate warning that wasn't part of -Wall but could

What's "unnecessary"? It's normal in GNU style to add extra parentheses
when their contents go over multiple lines, to help editors get
indentation right....
But not for things on a single line, like the ones I quoted:
+ && (cfun->machine->varargs_size == 0)
+ && (crtl->args.pretend_args_size == 0)
+ if ((fn != NULL) && fn->machine->optimize_call_stack)
etc.
