  "message": "Add strength reduction; for now replace multiply by power of 2\n\nCreate a new optimization pass, strength reduction, which will replace\ninteger multiplication by a constant power of 2 with an equivalent bit\nshift.  More changes could be added later.\n\n- Does not duplicate constants\n\n- Adds vector |Concat| utility function to a common test header.\n",
