            Bug ID: 152700
           Summary: We should be able to inline super calls to
                    InternalFunctions if we have inlined to the
                    construction site.

In general, when subclassing there is no way to know what the prototype of the created object is statically, as the new.target may change on each call. It is possible, however, if we inline to the construction site (i.e. the "new <function name>(...)" in JS) because then we might know the new.target statically.
