Thanks Zheng !! Your testcase is indeed more focused on the exact issue in `getSCEV`. 
I will wait to get more feedback on the correctness of the fix. Once it's decided that it's the correct fix, I will post an NFC review that adds your testcase with the "old behavior" expectations, and then this patch will amend the testcase.
