New tests added for these calls:

* evaluateOnCallFrame
* setAsyncCallStackDepth
* setBreakpoint
* setVariableValue

For setAsyncCallStackDepth, this change updates the test to manufacture async callstacks in a different way so that there is more than one. The previous promise chain method was broken by f61facfd.
