625 was used to allocate the space for the type structure itself. I.E.
626 if the type is on an objfile's type_obstack, then the space for data
627 associated with that type will also be allocated on the type_obstack.
628 If the type is not associated with any particular objfile (such as
629 builtin types), then the data space will be allocated with xmalloc,
630 the same as for the type structure. */
