Log:
        PR tree-optimization/26197
        * tree-ssa-alias.c (new_type_alias): Takes additional argument. Calls
        get_ref_base_and_extent and overlap_subvar to add only relevant
        subvars as may-aliases.
        (add_may_alias_for_new_tag): New function, factored out of
        new_type_alias.
        * tree-vect-transform.c (vect_create_data_ref_ptr): Call new_type_alias
        with additional argument.
        * tree-flow.h (new_type_alias): Takes additional argument.
