A thunk may perform either, or both, of the following operations:
- o Adjust the `this' pointer by a constant offset.

in the vtable.
- If both operations are performed, then the constant adjument to
- `this' is performed first.

+ class, and hence adds the offsets. A result pointer adjusting thunk
+ converts from a derived class to a base, and hence subtracts the
+ offsets. If both operations are performed, then the constant
+ adjument is performed first for this pointer adjustment and last
