As I mentioned in the previous outdated comment, `update_cc_test_checks.py` 
doesn't check return type even with `--function-signature`. However, the `ret` 
instruction at the end of the function can be used to verify the return type. 
In this case, it has `ret ptr addrspace(8) [[CALL]]` so the return type is `ptr 
addrspace(8)`.
