+ FUNCTION_DECL. The job of the thunk is to either adjust the this
+ pointer before transferring control to the FUNCTION_DECL, or call

+ pointer adjusting thunk must perform a call to the thunked
+ function, (or be implemented via passing some invisible parameter
+ to the thunked function, which is modified to perform the
+ adjustment just before returning).
+
A thunk may perform either, or both, of the following operations:
- o Adjust the `this' pointer by a constant offset.
- o Adjust the `this' pointer by looking up a vcall-offset
+ o Adjust the this or result pointer by a constant offset.
+ o Adjust the this or result pointer by looking up a vcall or vbase offset
in the vtable.
- If both operations are performed, then the constant adjument to
- `this' is performed first.
+ A this pointer adjusting thunk converts from a base to a derived
+ 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
+ for the result pointer adjustment.
