Sorry but I don't get the point. Currently most test cases in `Dialect/SCF/transform-opt.mlir` and `Dialect/SCF/loop-pipelining.mlir` satisfy `numIteration >= maxStage` thus `dynamicLoop = false`.

I added a test case that checks when a static loop does **not satisfy** `numIteration >= maxStage`, if I understand correctly.
