/*
Determine the set of methods that are overridden by the given
method.
In both Objective-C and C++, a method (aka virtual member function,
in C++) can override a virtual method in a base class. For
Objective-C, a method is said to override any method in the class's
base class, its protocols, or its categories' protocols, that has the same
selector and is of the same kind (class or instance).
If no such method exists, the search continues to the class's superclass,
its protocols, and its categories, and so on. A method from an Objective-C
implementation is considered to override the same methods as its
corresponding method in the interface.
For C++, a virtual member function overrides any virtual member
function with the same signature that occurs in its base
classes. With multiple inheritance, a virtual member function can
override several virtual member functions coming from different
base classes.
In all cases, this function determines the immediate overridden
method, rather than all of the overridden methods. For example, if
a method is originally declared in a class A, then overridden in B
(which in inherits from A) and also in C (which inherited from B),
then the only overridden method returned from this function when
invoked on C's method will be B's method. The client may then
invoke this function again, given the previously-found overridden
methods, to map out the complete method-override set.
Parameter cursor A cursor representing an Objective-C or C++
method. This routine will compute the set of methods that this
method overrides.
Parameter overridden A pointer whose pointee will be replaced with a
pointer to an array of cursors, representing the set of overridden
methods. If there are no overridden methods, the pointee will be
set to NULL. The pointee must be freed via a call to
clang_disposeOverriddenCursors().
Parameter num_overridden A pointer to the number of overridden
functions, will be set to the number of overridden functions in the
array pointed to by \p overridden.
