[Emit] clodule with recursive reference

[mhegazy]

module M{
  export class C {  }
  export module C {
    export var C = M.C
  }}

Expected:

var M;
(function (M) {
    var C = (function () {
        function C() { }
        return C;
    })();
    M.C = C;
    (function (_C) {
        _C.C = M.C;
    })(M.C || (M.C = {}));
    var C = M.C;
})(M || (M = {}));

Actual:

var M;
(function (M) {
    var C = (function () {
        function C() { }
        return C;
    })();
    M.C = C;
    (function (C) {
        C.C = M.C;
    })(M.C || (M.C = {}));
    var C = M.C;
})(M || (M = {}));
