[kdy1]

Description:

• The option hoist_props now does what it's supposed to do.
• Dropping of unused properties now does not drop properties too aggressively.
• The initializer of a dropped variable declaration is now properly visited.
• Indexing with string literals is not marked as a dynamic index anymore. This is required to handle codes like

  	var obj_foo = 1;
  	var obj_bar = 2;
  	function f() {
  	var obj = { foo: 3, bar: 4, "b-r": 5, "b+r": 6, "b!r": 7 };
  	console.log(obj_foo, obj.foo, obj.bar, obj["b-r"], obj["b+r"], obj["b!r"]);
  	}
  	f();
