This commit fixes the failure in the original PR when building with
shared libs. The problem is that `visitUsedValuesDefinedAbove` is
defined in `MLIRTransformUtils`, but that lib depends on this lib
(`MLIRAnalysis`). To fix, I dropped the use of
`visitUsedValuesDefinedAbove` and use `Region::walk` to traverse values
defined above.
