 *  The type maxconst returns information about the expression under
 *  consideration. The field self is true if the expression as a whole is
 *  constant within the program fragment under consideration. If the
 *  entire expression is not constant (self is false) then the field cont
 *  is a list of the sub-expressions which are constant within the
 *  specified region.
 *
 *  If no sub-expressions are constant, cont has the value nilexp.
 *
 *  If cont is not empty, its son is a list of elements, each of which
 *  has a son which is a constant within the specified program fragment.
 *  The pointer of cont points to the last element of the list.
