commit 422f11824b3abf6c71042e2ee3aed572f250fc89

    Replace hidden with versioned in elf_link_hash_entry

    This patch replaces the "hidden" field with the "versioned" field
    in
    elf_link_hash_entry so that we can avoid calling strchr and
    strrchr if
    the symbol is unversioned.

        * elf-bfd.h (elf_symbol_version): New enum.
        (elf_link_hash_entry): Replace hidden with versioned.
        * elflink.c (_bfd_elf_merge_symbol): Don't look for symbol
        version if the symbol is unversioned.  Initialize versioned.
        (_bfd_elf_add_default_symbol): Don't look for symbol version
        if the symbol is unversioned or hidden.  Initialize versioned.
        (elf_collect_hash_codes): Don't look for symbol version if the
        symbol is unversioned.
        (elf_collect_gnu_hash_codes): Likewise.
        (bfd_elf_gc_mark_dynamic_ref_symbol): Likewise.
        (_bfd_elf_link_hash_copy_indirect): Check versioned instead of
        hidden.
        (elf_link_output_extsym): Likewise.
