It also prevents enabling the strict mode of CFI which is currently disabled with -fsanitize-cfi-icall-generalize-pointers. The problematic casts are necessary to pass visit_type_T() and visit_type_T_members() as callbacks to qapi_clone() and qapi_clone_members(), respectively. Open-code these two functions to avoid the callbacks, and thus the type casts.
