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