[Bug objc/24868] New: objc-act.c builds non-type-safe structure

[sabre at nondot dot org]

The init_objc_symtab builds a structure with two short data members, but passes
NULL_TREE into build_int_cst.  These:

---
  /* cls_def_cnt = { ..., 5, ... } */
  initlist = tree_cons (NULL_TREE, build_int_cst (NULL_TREE, imp_count),
initlist);
  /* cat_def_cnt = { ..., 5, ... } */
  initlist = tree_cons (NULL_TREE, build_int_cst (NULL_TREE, cat_count),
initlist);
---

Should be changed to pass short_integer_type_node to build_int_cst instead of
NULL_TREE.  Passing NULL_TREE results in a 32-bit int.  This appears to not
cause a problem with the current code generator, but seems like a nasty latent
bug.
