  Changed paths:
    M llvm/lib/Target/AArch64/AArch64.h

    M llvm/lib/Target/AArch64/AArch64TargetMachine.cpp

  Log Message:
  -----------
  [llvm][AArch64ISelDAGToDAG] support -{start|stop}-{before|after}=aarch64-isel

Follow a similar pattern as AMDGPUDAGToDAGISel's constructor so that we
can use INITIALIZE_PASS to register a pass. This allows for more fine
grain testability of SelectionDAGISel via:

   llc -stop-{before,after}=aarch64-isel
