Benchmark: Test JS getter/setter

Script Preparation code:

var obj = {};

var _a = 1;

obj._a = 1;

obj.aGetter = function() {
  return _a;
}

obj.aSetter = function(val) {
  _a = val;
}

Object.defineProperty(obj, 'a', {
  enumerable: true,
  get: function () {
    return _a;  
  },
  set: function(val) {
    _a = val;
  }     
});

Tests:

obj.aSetter(2);
obj.aSetter(2);
obj.aGetter();
obj.aGetter();
obj.a = 2;
obj.a = 2;
obj.a;
obj.a;
