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.
