lto-symtab.c (lto_symtab_resolve_symbols): Preffer decl with constructor over decl without.
* lto-symtab.c (lto_symtab_resolve_symbols): Preffer decl with constructor
over decl without.
* cgraph.c (cgraph_remove_node): Clear also body of unanalyzed nodes.
* cgraph.h (varpool_can_remove_if_no_refs): Handle external correctly.

forgotten initializers.
