original commit message:
  Move function prototype handling into a special handler rather than IC

  Adjust hydrogen handling of function.prototype to be based on map feedback.
  Handle non-instance prototype loading using an IC rather than in the hydrogen

1539860866 Make landmines work on the first landmine. 
With the original script, landmines don't work if the initial commit of the landmine script and the first landmine are in the same build. In this case, the landmine file wouldn't exist yet and no landmine would be triggered. But the updated landmine content would have still been written, omitting the landmine.

Now, the script will initialize an empty landmine file if none exists. This will make sure that a landmine is set on the branch builders after the next branch point.

This also adds some debugging output to better trace when landmines are set/deleted.
