[XLA:Evaluator] Handle while loop.
* Add while loop support to HloEvaluator;
* Add a max_loop_iteration argument to the interpreter's constructor to limit
the number of loop iterations that will be evaluated (or no bound if -1).
Maintain current constant propagation behavior by setting limit to 0 for evaluators used for CP.
