Yup, exactly.  This is provided by the asm-printer-generator, so if you're 
using it, you should be good.  You don't need to be using the new dag isel 
stuff to use this.  If you look at the targets in mainline, the 
printInstruction method is automatically generated for them, which takes 
care of this.
