Fix several bugs:
  * Warnings were emitted all of the time and were really annoying
  * Functions could not be resolved unless they had external linkage.  Linkonce
    linkage was not allowed
  * ConstantPointerRef's were not handled when linking functions
    we now actually handle cast (CPR) to X -> cast (NewCPR) to X
