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

      Description

      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
