The first time I noticed the problem was after reordering some passes
on a local branch. cgraph_remove_unreachable_nodes was removing a node
with a low id. The inliner would then create a clone with the same
number.

I am not sure if this is the same reason why the libgomp.c++/for-4.C
now works on the branch.
