Maybe "Return NewInst with debug information copied from Original" would be
clearer?

"Return NewInst with" sounds a little bit like it makes a copy of NewInst.

As a compromise, I've put "Copy debug information from Original to NewInst, and
return NewInst."

+Instruction *CopyDebug(Instruction *NewInst, Instruction *Original);

 }
