The first couple of llc invocations mentioned in the document are wrong, and users will get confused about no output being written. Fix them.

 specify the machine copy propagation pass in the ``-stop-after`` option, as it
 runs just before the pass that we are trying to test:
 
-   ``llc -stop-after=machine-cp bug-trigger.ll > test.mir``

 If the same pass is run multiple times, a run index can be included
 after the name with a comma.
