#2498: RULES pragma broken in the head

This module:
{{{
module Foo where
{-# RULES "id" forall x. id x = x #-}
}}}
compiles fine with 6.8.3 but the HEAD says (twice):
{{{
Foo.hs:2:0: Unrecognised pragma
}}}
Adding `-frewrite-rules` has no effect. But with `-XRank2Types`, it
compiles fine for some reason.
