Thank you @lebedev.ri for guiding my huge code chunk in D104636 <https://reviews.llvm.org/D104636> into this patch that is more concise.
Also thank you @Whitney, @bmahjour, @qianzhen for reviewing my code.
I am now going to commit it.

Next I would work on the case when  `MemsetSizeSCEV != PointerStrideSCEV`. In this case, the SCEV-s can be folded given the loop entry is already protected by loop guard.
