5914 * c-common.c (c_common_attribute_table): Allow
5915 handle_visibility_attribute to be called for types.
5916 (handle_visibility_attribute) When given a type, set the visibility
5917 bits on the TYPE_NAME. When given a decl, don't set no_add_attrs
5918 so that we can check later whether the attribute was present. Added
5919 warning if attribute applied to non class type.
