    ld: Add _bfd_elf_link_hide_sym_by_version

    bfd_hide_sym_by_version can't be used to check if a versioned symbol is
    hidden.  This patch adds _bfd_elf_link_hide_sym_by_version to support
    both versioned and unversioned symbols by extracting versioned symbol
    check from _bfd_elf_link_assign_sym_version.
