Herman van Hovell f14ae4900a [SPARK-18300][SQL] Do not apply foldable propagation with expand as a child. ... ## What changes were proposed in this pull request? The `FoldablePropagation` optimizer rule, pulls foldable values out from under an `Expand`. This breaks the `Expand` in two ways: - It rewrites the output attributes of the `Expand`. We explicitly define output attributes for `Expand`, these are (unfortunately) considered as part of the expressions of the `Expand` and can be rewritten. - Expand can actually change the column (it will typically re-use the attributes or the underlying plan). This means that we cannot safely propagate the expressions from under an `Expand`. This PR fixes this and (hopefully) other issues by explicitly whitelisting allowed operators. ## How was this patch tested? Added tests to `FoldablePropagationSuite` and to `SQLQueryTestSuite`.
