Very good, thanks.

Well, we'd probably have to continue to accept the aarch64 LLVM IR intrinsic in the back-end to avoid breaking compatibility.  But that would still allow for adding a new target-independent LLVM IR intrinsic, and using that in clang common code to implement `__builtin_thread_pointer` for all platforms ...
