Arie Gurfinkel b120923dd5 qe_lite: bug fix in der::der_sort_vars() 
The case of

VAR 1 = (+ (:var 2) 10)
VAR 2 = (+ 0 foo)

was not properly handled whenever VAR2 has only one reference.
In that case, VAR2 is not marked as done when VAR1 is processed,
causing VAR2 to be duplicated in elimination order
