Creates a call target with a specific root node for this ternary operator such that the operator can be executed via a full call. This is in particular useful, if you want to execute an operator without a frame (e.g. from interop). It is not recommended to use this method directly. In order to enable AST sharing, you should use PythonLanguage.getOrCreateTernaryArithmeticCallTarget(TernaryArithmetic)
