* gdbtypes.h (TYPE_FLAG_VECTOR, TYPE_VECTOR): Define.
         * gdbtypes.c (recursive_dump_type): Output the vector flag.
         * dwarf2read.c (dwarf_attr_name): Handle new attribute for
         vectors.
         (read_array_type): Record the fact that this array type is really a
         vector (i.e. are passed in by value).
