Patch I am testing

Hi,
this patch adds sanity check that turns the nasty wrong code issue into ICE and
a hack to bb-reorder that should prevent it from placing EH landing pads very
first.  I am not quite sure this is robust enough, but can't think of better
fix. We may end up outputting extra NOP in case we fail to find right order.
