Hi,
I reverted the cgraph_remove_unreachable_nodes hunk.  It originally wasn't
supposed to be in the patch, I must've grabbed earlier version of it
(it also explains why I had to re-write changelog).

The change is correct, however gomp code keeps functions without properly inserting
them to callgraph across some time so I will submit separate patch for this.

My apologizes for the breakage.
Honza
