cgraph.c (cgraph_node::make_local): No name is unique during incremental linking.
* cgraph.c (cgraph_node::make_local): No name is unique during incremental linking. * cgraph.h (can_be_discarded_p): Update comment; also common and WEAK in named sections can be discarded; when doing incremental link do not rely on resolution being the final one. * varasm.c (default_binds_local_p_3, decl_binds_to_current_def_p): When symbol can be discarded, do not rely on resolution info. * symtab.c (symtab_node::nonzero_address): Take into account that symbol can be discarded. * ipa-visibility.c (update_visibility_by_resolution_info): Handle definition correctly. (function_and_variable_visibility): Do not set unique_name when incrementally linking. From-SVN: r231050
