  Log Message:
  -----------
  Fix interaction of CFI instructions with MachineOutliner.

1. When checking if a candidate contains a CFI instruction, actually
iterate over all of the instructions, instead of stopping halfway
through.
2. Make sure copied CFI directives refer to the correct instruction.
