[PATCH] D35931: [SCEV] Do not visit nodes twice in containsConstantSomewhere

[Max Kazantsev via Phabricator via llvm-commits]

Not obvious it is a win or not: we will have to check isDone() between all pushes, and only save pushing remaining operands for the last SCEV. If we traverse through a big graph where we will never find what we was looking for, we will only do extra checks without benefits.
