[PATCH] D33121: [SCEV] Fix sorting order for AddRecExprs

[Sanjoy Das via Phabricator via llvm-commits]

sanjoy added a comment.

I have two more comments:

- Can you also add an assert in `getAddExpr` checking that the expressions are sorted like we expected?
- Can you please add a comment in `CompareSCEVComplexity` on why the ordering is needed?  A one-liner that "we need this in getAddExpr" is sufficient.
