You might want to add a `cl::opt` to control the behavior as load-combine does, maybe?
See in `IPO/PassManagerBuilder.cpp`

  static cl::opt<bool> RunLoadCombine("combine-loads", cl::init(false),
                                      cl::Hidden,
                                      cl::desc("Run the load combining pass"));
