  13  * information about the tree.
  14  *
  15  * "guard" contains conditions that should still be enforced by
  16  * some ancestor of the current tree.  In particular, the already
  17  * generated tree assumes that these conditions hold, but may not
  18  * have enforced them itself.
  19  * The guard should not contain any unknown divs as it will be used
  20  * to generate an if condition.
  21  *
  22  * "enforced" expresses constraints that are already enforced by the for
  23  * nodes in the current tree and that therefore do not need to be enforced
  24  * by any ancestor.
  25  * The constraints only involve outer loop iterators.
