Statements like SELECT, INSERT, and UPDATE also optionally include this
list, so move its parsing out of parse_delete_statement(). Since it will
appear before the actual statement, parse it first in next_statement();
then only parse for statements that are allowed to include the list.
Misread the graph: In the "WITH [RECURSIVE] common-table-expression"
section, common-table-expression is actually a repeating list. This
changes the parser to correctly parse this section as a list. Create a
new AST node, CommonTableExpressionList, to store both this list and the
boolean RECURSIVE attribute (because every statement that uses this list
also includes the RECURSIVE attribute beforehand).
