LGTM as this simplifies things slightly by avoiding a Value <-> SCEV roundtrip. Please wait a day or so with committing in case other reviewers have additional thoughts.

                                        PredicatedScalarEvolution *PSE) {

+  const DenseMap<Value *, const SCEV *> &Strides =
+    DenseMap<Value *, const SCEV *>();
----------------
