A questionable predicate in sh/predicates.md

[Kazu Hirata]

Hi,

In sh/predicates.md, I see

(define_predicate "sh_rep_vec"
  (match_code "const_vector")
{
  int i;
  rtx x, y;

  if ((GET_CODE (op) != CONST_VECTOR && GET_CODE (op) != PARALLEL)
      || (GET_MODE (op) != mode && mode != VOIDmode))
    return 0;

Notice that match_code at the beginning does not mention PARALLEL, but
we have GET_CODE (op) != PARALLEL later.  Is this predicate intended
to accept PARALLEL as well?  If so, should we change the match_code at
the beginning?  When I did the conversion from PREDICATE_CODES to
predicates.md, I did so in a mechanical way, so loose things like this
might have gone unnoticed.
