Scope the inference to the current bound node when inferring instances of classes

When inferring instances of classes from arguments, such as ``self``
in a bound method, we could use as a hint the context's ``boundnode``,
which indicates the instance from which the inference originated.
As an example, a subclass that uses a parent's method which returns
``self``, will override the ``self`` to point to it instead of pointing
to the parent class.
