Add the clang library to the repo (with some of my changes, too).

+
+// 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).
