        * module.c (check_access): Return true if new static flag
        'dump_smod' is true..
        (gfc_dump_module): Rename original 'dump_module' and call from
        new version. Use 'dump_smod' rather than the stack state to
        determine if a submodule is being processed. The new version of
        this procedure sets 'dump_smod' depending on the stack state and
        then writes both the mod and smod files if a module is being
        processed or just the smod for a submodule.
        (gfc_use_module): Eliminate the check for module_name and
        submodule_name being the same.
        * trans-decl.c (gfc_finish_var_decl, gfc_build_qualified_array,
        get_proc_pointer_decl): Set TREE_PUBLIC unconditionally and use
        the conditions to set DECL_VISIBILITY as hidden and to set as
        true DECL_VISIBILITY_SPECIFIED.
