  Log Message:
  [InstCombine] remove likely redundant ValueTracking-based folds for shifts

This is not expected to have a functional difference as discussed in the
post-commit comments for 8a9c70fc01e6. All of the motivating tests for
the older fold still optimize as expected because other code can infer
the 'nuw'.
