Log:
        * tree-vect-transform.c (vect_create_addr_base_for_vector_ref): Takes
        additional argument loop. Updated the function documentation. Handle
        the 'nested_in_vect_loop' case (the case when the dataref is in an
        inner-loop nested in an outer-loop that is now being vectorized).
        (vect_create_data_ref_ptr): Call vect_create_addr_base_for_vector_ref
        with additional argument. Handle the 'nested_in_vect_loop' case.
        (vectorizable_load): Handle the 'nested_in_vect_loop' case.
        (vectorizable_store): Handle the 'nested_in_vect_loop' case.
        (vect_gen_niters_for_prolog_loop): Call
        vect_create_addr_base_for_vector_ref with additional argument.
        (vect_create_cond_for_align_checks): Likewise.
        * tree-vect-analyze.c (vect_compute_data_ref_alignment): Handle the
        'nested_in_vect_loop' case.
        (vect_analyze_data_ref_access): Likewise.
        (vect_analyze_data_refs): Likewise. Call split_constant_offset.
        * tree-vectorizer.c (new_stmt_vec_info): Initialize new fields.
        (vect_supportable_dr_alignment): Handle the 'nested_in_vect_loop' case.
        * tree-vectorizer.h (_stmt_vec_info): Added new fields:
        dr_base_address, dr_init, dr_offset, dr_step, and dr_aligned_to, along
        with new access functions for these fields: STMT_VINFO_DR_BASE_ADDRESS,
        STMT_VINFO_DR_INIT, STMT_VINFO_DR_OFFSET, STMT_VINFO_DR_STEP, and
        STMT_VINFO_DR_ALIGNED_TO.
        * tree-data-refs.c (split_constant_offset): New (brought over from
        mainline).
        * tree-data-refs.h (split_constant_offset): Likewise.
