Make DDC a better platform for debugging by ensuring that stack traces generated by DDC even when using the raw dart:core StackTrace class apply JS source maps and benefit from the polish provided by the stack_trace package. stack_trace_mapper.dart needs to be compiled to js and included on your page to benefit from this functionality. Otherwise you will still see regular JS stack traces as usual. BUG= R=vsm@google.com Review-Url: https://codereview.chromium.org/2735303002 .
