Hi fhahn! Thank you for your review. I'll consider your questions and comments carefully.
Firstly, for the No.2, I think we can do the checks after `MemoryDepChecker::isDependent` returned `Dependence::Backward` ，and extend the `MemoryDepChecker::Dependence` struct to save the reorder list. What do you think about?
