Integrate iOS specific changes in the core domdistiller.js

Integrate iOS specific changes in the core domdistiller.js

The file in iOS was just a modified copy and diverged over time. Moved
the if from the grd file to the core js file in order to allow for easier
maintenance.

Could you please do this in the dom-distiller repo instead? That would be more
better.

Hu, no. I need to do this here first, to change the grdp file. Then the file can
move into the other repository (where I still can't commit BTW).

okay, let's do this as the first step to consolidate these two approaches in the
