Save Mach as Cfg after Selection #624

  • Add an option select to the existing compiler flag -save-ir-after.
  • If flag "-save-ir-after select" is provided, call cfgize after Selection to convert Mach to Cfg and then save it to a file.

There is no file format to save Mach to a file (as an IR, not in textual form like we get from -dsel). This is useful for debugging (cfg can be printed to .dot format that is easy to follow) and other tools that operate on CFGs can use it.
