[Bug c/33329] ICE in expand_simple_binop, at optabs.c:1294

Also ICEs on i686-pc-linux-gnu with -msse2.

The problem is again in:

--cut here--
rtx
expand_simple_binop (enum machine_mode mode, enum rtx_code code, rtx op0,
                     rtx op1, rtx target, int unsignedp,
                     enum optab_methods methods)
{
  optab binop = code_to_optab[(int) code];
  gcc_assert (binop);

  return expand_binop (mode, binop, op0, op1, target, unsignedp, methods);
}
--cut here--

code_to_optab returns NULL for (unsupported) VEC_SELECT code. IIRC, we already
have some discussion about this issue.

The backtrace is:
