----------------
This may be a bit too flexible.  The CHECK-DAG here would allow the two instructions above to be swapped, in which case the semantics would be incorrect.

The same holds for a number of other tests below.   Maybe a better way would be to use auto-generated CHECK statements for this file?  (Via utils/update_llc_test_checks.py)
