tree-vect-transform.c (vect_create_epilog_for_reduction): Takes an additional argument.

2008-08-14  Dorit Nuzman  <dorit@il.ibm.com>

        * tree-vect-transform.c (vect_create_epilog_for_reduction): Takes an
        additional argument. Support reduction when duplication is needed due
        to data-types of different sizes in the loop.
        (get_initial_def_for_induction): Fix printout.
        (vect_get_vec_def_for_stmt_copy): Support case where the
        vec_stmt_for_operand is a phi node.
        (vectorizable_reduction): Support reduction when duplication is needed
        due to data-types of different sizes in the loop.
        (vectorizable_call): Remove restriction to not vectorize in case we
        have data-types of different sizes in the loop.
        (vectorizable_conversion): Likewise.
        (vectorizable_operation): Likewise.
        (vectorizable_type_demotion): Likewise.
        (vectorizable_type_promotion): Likewise.
        (vectorizable_induction): Add restriction to not vectorize in case
        we have data-types of different sizes in the loop.
