Technically, it is possible. However, we don't yet have layout tests that stop
in debugger, so various problems are likely to arise.

Scenario for the test would be:
- In the layout test page, create a function that has debugger; statement.
That's pretty much all you do on the layout page side, rest is happening on the
inspector front-end.
- On the front-end side, enable debugger (this is done synchronously) and
execute the function you created in previous step using
InjectedScriptAccess.evaluate.
- Just before you do this evaluate, add a sniffer that would give your code
control upon WebInspector.pausedScript call from the backend.
- As soon as pausedScript is called, get a reference to the call frame.
- Either synchronously or in setTimeout(0) execute
InjectedScriptAccess.evaluateInCallFrame against your call frame with "x"
expression.

tests are located under LayoutTests/inspector
