H.J. Lu 099bb8fb97 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.

bfd/

	PR ld/23194
	* elf-bfd.h (_bfd_elf_link_hide_sym_by_version): New.

	Extracted from _bfd_elf_link_assign_sym_version.
	(_bfd_elf_link_hide_sym_by_version): New function.
	(_bfd_elf_link_assign_sym_version): Use

	* elfxx-x86.c (_bfd_x86_elf_link_symbol_references_local): Call
	_bfd_elf_link_hide_sym_by_version instead of
	bfd_hide_sym_by_version.  Don't check unversioned symbol.
