There is an `includeSources` option today to skip writing both source bytes as well as the line starts. Dart2JS needs the line starts to generate source maps from its modified dill. But the actual bytes aren't used passed a certain point. This new option would allow us to exclude the information we don't need from the dill. For large applications this can reduce the size of the dill by close to 50%.
