to declare that they preserve other passes without needing to pull in
additional header file or library dependencies. Convert MachineFunctionPass

4306963170 In instcombine's debug output, avoid printing ADD for instructions that are 
already on the worklist, and print Visited when an instruction is about to be
visited.  Net, on one input, this reduced the output size by at least 9x.
