AIX: use align 8 for byval parameter

On AIX, byval pointer arguments are aligned to 8 bytes based on the 64bit register size. For example, the C callee https://godbolt.org/z/5f4vnG6bh will expect the following argument.

```
ptr nocapture noundef readonly byval(%struct.TwoU64s) align 8 %0
```

This case is captured by `run-make/extern-fn-explicit-align`
