* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15204 91177308-0d34-0410-b5e6-96231b3b80d8
