Good question. To date I have only scratched the surface of JavaScriptCore.
So I took a look at this. It looks to me like JSC emits a possible debugger
breakpoint message after each statement. And the location data provided
for that statement (firstLine() and lastLine()) are originally set in the grammar
via a call to setLoc(). So it would involve a change would need to be made to
JavaScriptCore's grammar / parser.

Incidentally there is already work underway for improvements to the parser:

@Oliver Hunt and Zoltan Herczeg, how difficult do you think this would be
to add to your new JavaScript parsers or even the existing parser? I would
appreciate your expert opinions!
