Use SFINAE to generalize << overloads, give 'constant' a pretty form,
generalize the asmprinters handling of pretty names to allow arbitrary sugar to
be dumped on various constructs. Give CFG function arguments nice "arg0" names
like MLFunctions get, and give constant integers pretty names like %c37 for a
constant 377
