OK, the funny inconsistency comes from the fact that we always eliminate COMDAT
variables, but we keep around static variables with -fno-toplevel-reorder.
-O0 imply -fno-toplevel-reorder and -fwhole-program brings COMDAT variables
local, just like in this case.

This all envolved for historical reasons.  I wonder how we really want to
behave here...

I am looking into the LTO case. With new plugin API it should just work.
