  Log Message:
  -----------
  [AArch64][MachineOutliner] Don't outline CFI instructions

CFI instructions can only safely be outlined when the outlined call is a tail
call, or when the outlined frame is fixed up.

For the sake of correctness, disable outlining from CFI instructions.

Add machine-outliner-cfi.mir to test this.
