[libclang] Introduce clang_Cursor_isDynamicCall which,
given a cursor pointing to a C++ method call or an ObjC message,
returns non-zero if the method/message is "dynamic", meaning:
For a C++ method: the call is virtual.
For an ObjC message: the receiver is an object instance, not 'super' or a
specific class.
