`affine::replaceForOpWithNewYields` and `replaceLoopWithNewYields` (for "scf.for") are now interface methods and additional loop-carried variables can now be added to "scf.for"/"affine.for" uniformly. (No more `TypeSwitch` needed.) Note: `scf.while` and other loops with loop-carried variables can implement `replaceWithAdditionalYields`, but to keep this commit small, that is not done in this commit.
