[PATCH] D19054: [SystemZ] Support __builtin_thread_pointer.

[Marcin Kościelnicki via llvm-commits]

koriakin added a comment.

This serves two purposes:

- __builtin_thread_pointer can be used from clang
- llvm.s390.thread.pointer can be used in IR, allowing us to implement proper stack protector support (aiming at TLS instead of __stack_chk_guard)
