Run fails with GEP is not of right type for indices for PreservedValueRegistry example. #2

The following code should illustrate how to use the preserved value registry

  auto arg1 = ConstantInt::get(Type::getInt32Ty(M.getContext()), static_cast<uint64_t>(1));
  auto arg2 = ConstantInt::get(Type::getInt32Ty(M.getContext()), static_cast<uint64_t>(2));
  PreservedValueRegistry::Register("comp-analysis",
                                   arg1,
                                   [this](const std::string &pass, llvm::Value *oldV, llvm::Value *newV) {
                                     //assert ( false );
                                   });
  arg1->replaceAllUsesWith(arg2);

However, if it is used then tetris example fails with this error.
