// There are basically four ways that we end up doing message dispatch for the
// NeXT runtime. They are:
// (1) fragile ABI, legacy dispatch
// (2) non-fragile ABI, legacy dispatch
// (2) non-fragile ABI, non-legacy dispatch
// (2) non-fragile ABI, mixed dispatch
//
// Note that fragile ABI and non-fragile ABI legacy dispatch are not the same,
// they use some different API calls (objc_msgSendSuper vs objc_msgSendSuper2).
