decorator expression to call/apply expression

[wuliang142857]

before

// test code: 
function test(name) {
    return function (target) {
        return target;
    };
}

function foo(target) {
   return target;
}

class Bar {
    getName(@test("name") name1) {
        return name1;
    }

     getFoo(@foo name1) {
        return name1;
    }
}

// the transform Bar#getName like
function getName(_name2) {
    var _name3 = test("name")(_name2);
    return _name3;
}

// the transform Bar#getFoo like
function getFoo(_name2) {
    var _name3 = test(_name2);
    return _name3;
}

now

// the transform Bar#getName like
function getName(_name2) {
    var _name3 = test.call(this, "name").call(this, _name2);
    return _name3;
}

// the transform Bar#getFoo like
function getFoo(_name2) {
    var _name3 = test.bind(this).call(this, _name2);
    return _name3;
}

then we can visit properties of Bar in parameter decorators.

thanks

Tests appear to be failing in TravisCI. Do you have any indication as to why this might be?
