  Changed paths:
    M llvm/lib/ExecutionEngine/JITLink/EHFrameSupport.cpp
    M llvm/lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp

  Log Message:
  -----------
  [SystemZ/ZOS]__(de)register_frame are not available on z/OS.

The functions `__register_frame`/`__deregister_frame` are not
available on z/OS, so add a guard to not use them.
