(all_symbols_read_handler): Add -flinker-output option.
(onload): Record linker_output info.

hidden symbols may be still used later.
(update_visibility_by_resolution_info): Do not drop weak during
incremental link.
(function_and_variable_visibility): Fix formating.
* flag-types.h (lto_linker_output): Declare.
* common.opt 9flag_incremental_link): New flag.
