This change causes the following problem to appear when building
builtin.m in non-C grades.

make_hlds_passes.m:183 succeeds on compiler_generated_rtti_for_builtins,
so we call add_builtin_type_ctor_special_preds for the type_ctors in
builtin_type_ctors_with_no_hlds_type_defn, e.g. builtin.int/0.

classify_type_ctor gets called, which knows about unqualified("int")/0,
but not builtin.int/0.  It tries to look that up in the type definition
table, but aborts because it doesn't exist.

How should I fix this?
