uses the modifier "%ld".  Now lli passes off "%lld" to the underlying runtime
library in this case.

   - Reenable gep (gep x) -> x
   - Make instcombine do dead instruction elimination where it's really
     easy.  Now visitors don't have to ensure they aren't not processing
     dead instructions.

If instcombine is making dead instructions, ALL that should be used is -die
