@pmwhite, this PR changes how we translate control flow to javascript. It can affect compilation time, size of generated files, and runtime performance. Let me know if you have time to test this and report positive and negative impact. |

@vouillon, I think the diff is ready for review, commit history is not and will be squashed. |

|
@vouillon, I've cleaned up the commit history. |

This looks good to me. |

Sorry, I have not gotten to testing this yet. I will let you know the results when I do. |
