For CFN_BUILT_IN_ICEIL, the modifier is narrow, and currently vectorizable_=
call
require op_in and op_out to be simple_integer_narrowing, which means it fai=
ls
to go the direct internal fn way.

---------cut from vectorizable_call-----------
  tree_code convert_code =3D ERROR_MARK;
  if (cfn !=3D CFN_LAST
      && (modifier =3D=3D NONE
          || (modifier =3D=3D NARROW
              && simple_integer_narrowing (vectype_out, vectype_in,
                                           &convert_code))))
    ifn =3D vectorizable_internal_function (cfn, callee, vectype_out,
                                          vectype_in);
-----------cut end----------------------

Similar for CFN_BUILT_IN_LCEIL under 32-bit target.
For 64-bit target CFN_BUILT_IN_LCEIL, CFN_BUILT_IN_LLCEIL will go the direct
internal fn way, add lceilmn2 expanders works.

Not sure whether vectorizable_call should be extended or just leave
CFN_BUILT_IN_ICEIL/IFLOOR/IRINT/IROUND part in
ix86_builtin_vectorized_function.=
