Herman van Hovell c604d659e1 [SPARK-23951][SQL] Use actual java class instead of string representation. ... ## What changes were proposed in this pull request? This PR slightly refactors the newly added `ExprValue` API by quite a bit. The following changes are introduced: 1. `ExprValue` now uses the actual class instead of the class name as its type. This should give some more flexibility with generating code in the future. 2. Renamed `StatementValue` to `SimpleExprValue`. The statement concept is broader then an expression (untyped and it cannot be on the right hand side of an assignment), and this was not really what we were using it for. I have added a top level `JavaCode` trait that can be used in the future to reinstate (no pun intended) a statement a-like code fragment. 3. Added factory methods to the `JavaCode` companion object to make it slightly less verbose to create `JavaCode`/`ExprValue` objects. This is also what makes the diff quite large. 4. Added one more factory method to `ExprCode` to make it easier to create code-less expressions. ## How was this patch tested? Existing tests.
