[PATCH] D62990: [SCEV]When safe, compute MinStart as unsigned_min(Start - Stride) + Stride in computeMaxBECountForLT

[Z. Zheng via Phabricator via llvm-commits]

For the case in this issue, Start and L are not enough, we also need Stride, to calculate correct MinStart, requiring getUnsignedRangeAtScope() take to SCEV* parameters, I think it's a little confusing.
