* tree-ssanames.c (duplicate_ssa_name_ptr_info): New function.

        (duplicate_ssa_name): Call duplicate_ssa_name_ptr_info.
        * tree-vect-analyze.c (vect_object_analysis): additional parm
        pass back a "struct ptr_info_def *" with the points-to info.
        (vect_analyze_data_refs): set the STMT_VINFO_PTR_INFO for the
        statement using info returned from vect_object_analysis.
        * tree-vect-transform.c (update_vuses_to_preheader): New function.
        (vect_create_data_ref_ptr): Remove updates to vars_to_rename
        for virtual uses and defs when creating a replacement vector
        reference.  Call duplicate_ssa_name_ptr_info to define points-to
        info for vector pointer replacement using STMT_VINFO_PTR_INFO.
        (vectorizable_store): copy_virtual_operands and update
        definition statements.
        (vectorizable_load): copy_virtual_operands.  Remove call to
        mark_call_clobbered_vars_to_rename for call to "const" builtin.
        * tree-vectorizer.c (vectorize_loops): Remove calls to
        rewrite_into_ssa and bitmap_clear (vars_to_rename).
        (new_stmt_vec_info): initialize STMT_VINFO_PTR_INFO for stmt.
        * tree-vectorizer.h (_stmt_vec_info): add field ptr_info and
        define macro STMT_VINFO_PTR_INFO for use in accessing.
        * tree.h add export of duplicate_ssa_name_ptr_info.
        * rs6000.c (altivec_init_builtins): Declare builtin function
        __builtin_altivec_mask_for_load to be "const".
