[PATCH] D71539: [SCEV] Look through trivial PHIs.

[Bardia Mahjour via Phabricator via llvm-commits]

bmahjour added a comment.

`DependenceInfo::classifyPair` in DA incorrectly classifies the subscripts in the above test case as SIV, where it used to classify them as non-linear (because one of the subscripts was not an AddRec). In theory we should be able to threat them as MIV I think.
