I think we should be clear about semantic of "references to arguments passed to
such parameters" in the doc.
Similar to lifetimebound, I think we have 3 major cases:
- a reference parameter, we consider its referenced object;
- a pointer parameter, we consider its pointee object;
- a pass-by-value struct parameter, we assume this struct is pointer-like
object, we consider objects that its transitive subobjects refer to;
