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.

Fixed by:

PR objc/44140
(init_objc_symtab): Use integer_zero_node, make the short
integer type specific on relevant nodes.
