New assert in haifa-sched.c

[Adam Nemet]

haifa-sched.c:
  2302        /* Let the target filter the search space.  */
  2303        for (i = 1; i < ready->n_ready; i++)
  2304          if (!ready_try[i])
  2305            {
  2306              insn = ready_element (ready, i);
  2307  
  2308              gcc_assert (INSN_CODE (insn) >= 0
  2309                          || recog_memoized (insn) < 0);

I am hitting this assert with the Octeon pipeline patch.  Isn't the check on
recog_memoized reversed?  Or are we really asserting here that the insn has
either been recognized earlier or won't be recognized now either?!
