I think the idea is to keep NDEBUG out of headers when possible. So I think this should better be something like:

-#ifndef NDEBUG
   void dumpUses(unsigned RegNo) const;

to be inline with various other dumpers (like MachineInstr::dump(), Pass::dump(), ...)

If that works for you please submit a patch to phabricator as described in http://llvm.org/docs/DeveloperPolicy.html#making-and-submitting-a-patch
