Debugger doesn't print values of Map type

````
class Test {
private var map:Map;

public function new() {
map = [1 => 1, 2 => 2];
trace(map);
}
````

In debugger output
````
print this.map

this.map : haxe.ds.IntMap =
{
h : Dynamic = ...
}

6> print this.map.h

this.map.h : Dynamic =
{
}
````

Start with the Test class reproducer and inspect the debugger output for this.map, which currently shows an empty internal h value instead of the entries. Reproduce the Map inspection and confirm that its stored keys and values, including 1=>1 and 2=>2, are displayed when done.
