Some comments get stripped out of JS output

[alvarorahul]

The following TS file

export = Main;
module Main {
    // Test 1

    class Foo {
        // Test 2
        public bar = 5;
        // Test 3
        }

    // Test 4
}

produces the following JS output

define(["require", "exports"], function (require, exports) {
    var Main;
    (function (Main) {
        // Test 1
        var Foo = (function () {
            function Foo() {
                // Test 2
                this.bar = 5;
            }
            return Foo;
        })();
    })(Main || (Main = {}));
    return Main;
});

NOTE that the comments // Test 3 and // Test 4 are not present

I would expect that all comments in the TS file are preserved in the generated JS file
