It may be worth adding one more test case to check that tied operands are
handled properly. Something along the lines
```llvm
%tmp = call i64 @llvm.ptrauth.auth(i64 %arg1, i32 0, i64 %arg)
```
i.e. operands are swapped - to test that one `mov` is still emitted:
```
autia x1, x0
mov x0, x1
ret
```
As we do not test the mapping of keys to real instructions, one test case
mentioning an arbitrary key should be enough.
