Simon Zünd 44a8a7d685 Introduce v8::StackTrace::CurrentScriptNameOrSourceURL 
This CL introduces a dedicated API to retrieve the current (w.r.t. the
JS stack) script name or sourceURL. Currently, API clients will
collect multiple stack traces in increasing sizes to accomplish the
same goal. The new method walks the JS stack in the same way as the
stack trace collection mechanic but doesn't create/allocate stack info
or callsite objects along the way.
