Remove precedence hacks no longer needed without postfix operators. It's no longer necessary to assign explicit precedences to GENERATED, NULL_P, PRESERVE, or STRIP_P.
Actually, we don't need to assign precedence to IDENT either; that was really just there to govern the behavior of target_el's "a_expr IDENT" production, which no longer ends with that terminal. However, it seems like a good idea to continue to do so, because it provides a reference point for a precedence level that we can assign to other unreserved keywords that lack a natural precedence level. Research by Peter Eisentraut and John Naylor; comment rewrite by me.
