[Quentin Colombet via Phabricator via llvm-commits]

> Bug fix: ScalarEvolution::getAddExpr() may modify the vector of SCEVs it is given as argument, causing 2nd formula to be created with only part of the SCEVs in Ops.
>  This patch fixes this by using a temporary copy of Ops for the 1st formula.

Is this covered by an existing test case?
If not, could you add one?
