--- Comment #33 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That would indeed simplify things and auto_vec member would be unnecessary, nor
any of the length/allocated members etc.  All we'd need is just a pointer and
small size buffer (and is_small check would be pointer == &small_size_buffer).
