tree-flow.h (stmt_ann_d): Move aux to ...

        * tree-flow.h (stmt_ann_d): Move aux to ...
        (tree_ann_common_d): ... here.
        * tree-ssa-loop-im.c (LIM_DATA, determine_invariantness_stmt,
        move_computations_stmt, schedule_sm): Update references to
        aux.
        * tree-vectorizer.h (set_stmt_info, vinfo_for_stmt): Likewise.
        * tree-vect-transform.c (vect_create_index_for_vector_ref): Update
        call to set_stmt_info.
        (vect_transform_loop): Likewise.
        * tree-vectorizer.c (new_loop_vec_info, destroy_loop_vec_info):
        Likewise.

        * tree-vect-analyze.c (vect_analyze_scalar_cycles): Made void instead of
        bool.
        (vect_mark_relevant): Takes two additional arguments - live_p and
        relevant_p. Set RELEVANT_P and LIVE_P according to these arguments.
        (vect_stmt_relevant_p): Differentiate between a live stmt and a
        relevant stmt. Return two values = live_p and relevant_p.
        (vect_mark_stmts_to_be_vectorized): Call vect_mark_relevant and
        vect_stmt_relevant_p with additional arguments. Phis are no longer
        put into the worklist (analyzed seperately in analyze_scalar_cycles).
        (vect_determine_vectorization_factor): Also check for LIVE_P, because a
        stmt that is marked as irrelevant and live, cause it's only used out
        side the loop, may need to be vectorized (e.g. reduction).
        (vect_analyze_operations): Examine phis. Call
        vectorizable_live_operation for for LIVE_P stmts. Check if
        need_to_vectorize.
        (vect_analyze_scalar_cycles): Update documentation. Don't fail
        vectorization - just classify the scalar cycles created by the loop
        phis. Call vect_is_simple_reduction.
        (vect_analyze_loop): Call to analyze_scalar_cycles moved earlier.
        * tree-vect-transform.c (vect_create_index_for_vector_ref): Update
        call to set_stmt_info.
        (vect_get_vec_def_for_operand): Code reorganized - the code that
        classifies the type of use was factored out to vect_is_simple_use.
        (vectorizable_store, vect_is_simple_cond): Call vect_is_simple_use with
        additional arguments.
        (vectorizable_assignment): Likewise. Also make sure the stmt is relevant
        and computes a loop_vec_def.
        (vectorizable_operation, vectorizable_load, vectorizable_condition):
        Likewise.
        (vectorizable_live_operation): New.
        (vect_transform_stmt): Handle LIVE_P stmts.
        * tree-vectorizer.c (new_stmt_vec_info): Initialize the new fields
        STMT_VINFO_LIVE_P and STMT_VINFO_DEF_TYPE.
        (new_loop_vec_info, destroy_loop_vec_info): Also handle phis.
        (vect_is_simple_use): Determine the type of the def and return it
        in a new function argument. Consider vect_reduction_def and
        vect_induction_def, but for now these are not supported.
        (vect_is_simple_reduction): New. Empty for now.
        * tree-vectorizer.h (vect_def_type): New enum type.
        (_stmt_vec_info): Added new fields - live and _stmt_vec_info.
        (STMT_VINFO_LIVE_P, STMT_VINFO_DEF_TYPE): New accessor macros.
        (vect_is_simple_use): New arguments added to function declaration.
        (vect_is_simple_reduction): New function declaration.
        (vectorizable_live_operation): New function declaration.

        * tree-vect-analyze.c (vect_can_advance_ivs_p): Add debug printout.
        (vect_can_advance_ivs_p): Likewise.
        * tree-vect-transform.c (vect_update_ivs_after_vectorizer): Likewise.
