History
Chris Lattner 70e9b59b0e * Substantially simplify how free instructions are handled (potentially fixing 
a bug in DSE).
* Delete dead operand uses iteratively instead of recursively, using a
  SetVector.
* Defer deletion of dead operand uses until the end of processing, which means
  we don't have to bother with updating the AliasSetTracker.  This speeds up
  DSE substantially.
