    M llvm/lib/ExecutionEngine/Orc/ObjectLinkingLayer.cpp

  Log Message:
  -----------
  [ORC] Add a mutex to guard EHFrameRegistrationPlugin data structures.

These may be accessed from multiple threads if concurrent materialization is
enabled in ORC.

Testcase coming in a follow-up patch that enables eh-frame registration for
LLJIT.

  Log Message:
  -----------
  [ORC] Enable exception handling in JIT'd code when using LLJIT on Darwin.

This patch enables exception handling in code added to LLJIT on Darwin by
adding an orc::EHFrameRegistrationPlugin instance to the ObjectLinkingLayer
(which is currently used on Darwin only).
