[Bug c/25795] New: Proccessing the attribute externally_visible too early

[pinskia at gcc dot gnu dot org]

extern const char *mystr;       /* normally in a header */
const char *mystr __attribute__ ((externally_visible));
----------------------------------------
What happens is that we call cgraph_varpool_node from
handle_externally_visible_attribute
which adds the "second" decl (which will not exist soon).  And then we do a
merge with the second and first decls and get back the first decl and then we
use the first decl always.
