Debugger tests

Here is a simple Debugger test:

var g = newGlobal('new-compartment');
var dbg = new Debugger(g);
var c;
dbg.onDebuggerStatement = function (frame) {
    c = frame.eval("2 + 2");
};
g.eval("debugger;");
assertEq(c.return, 4);

Let’s step through this example line by line and see how it works.
