I think you need to explain why this change is desirable/necessary for LTO, 
this would be a good starting point.  As for setting TREE_ADDRESSABLE on every 
single global symbol in every single front-end, why not, but this seems more 
complicated than treating global symbols as so by default (in non-LTO mode).
