Uncaught exceptions in worker threads are shown in the console, with the location of the place the exception was thrown from but no stack trace.

Using this test page https://melodic-client-1.glitch.me/, I don't even see the location.
The error object is created in dom/workers/WorkerError.cpp#487-491, using a nsScriptError, where it could use a nsScriptErrorWithStack I guess?
Brian, would you mind checking if this can be fixed quickly? Thanks!

I was working on this yesterday and should have a patch later today. We do need to use nsScriptErrorWithStack, but the tricky part is getting the stack info from the worker thread to the main thread (where the nsScriptErrorWithStack is created).
