Move the code in TargetPassConfig::addPass that inserts machine printer pass to

the overloaded version of addPass which takes Pass*.

This change enables inserting the machine printer pass when the overloaded
version of addPass that takes Pass* is called to add a pass, instead of the
one which takes AnalysisID. I need this to prevent make-check tests from
failing when I commit another patch later.
