Nuno Lopes a302c2f15e fix crashes in elim-uncnstr2 
This would crash before:
(declare-fun x () (_ BitVec 4))
(assert (not (bvule x #x1)))
(apply elim-uncnstr2)

That's because the index_set iterator was querying qtail to compute the end of the iteration
But the problem is that elim-uncnstr2 may add new fmls to the goal, as in this case.
The bvule is replaced with an 'or', but since it's negated, it turns into 2 goals
Solve the issue by freezing the qtail for the iteration loop.
This is the right behavior for elim-uncnstr2, as it can't rewrite exprs that haven't been analyzed before

@NikolajBjorner please check if this the right behavior for the other simplifiers. Thank you
