This ought to suggest why a port would need to do this, namely if
registers can be larger than void*.

I still think that assuming extended context should be a separate target
macro which is implied by REG_VALUE_IN_UNWIND_CONTEXT, but can also be
defined separately by new ports.
Otherwise it looks good to me.
