Clean up debug printing of the abstract syntax trees after parsing, binding and optimization

---------------------------------------------------------------------------------------------

                 Key: DERBY-4087
                 URL: https://issues.apache.org/jira/browse/DERBY-4087
             Project: Derby
          Issue Type: Improvement
          Components: Miscellaneous, SQL
            Reporter: Dag H. Wanvik
            Priority: Trivial


Currently, the printing is often inconsistent:

- some subtrees not printed
- wrong indentation due to missing newlines, or lacking level increments
- redundant printing of subtrees (AST is really a DAG, would be nice to print only once and
then refer back to show aliasing)
- some items printed twice due to inconsistent usage of pattern
