* elf64-ppc.c (struct _ppc64_elf_section_data): Delete t_symndx,

	* elf64-ppc.c (struct _ppc64_elf_section_data): Delete t_symndx,
	add toc.symndx and toc.add.
	(ppc64_elf_check_relocs): Don't set htab->tls_get_addr here.
	Set up toc.add.
	(get_tls_mask): Add toc_addend param, set from toc.add.  Adjust all
	callers.
	(ppc64_elf_tls_setup): Set htab->tls_get_addr and tls_get_addr_fd.
	(branch_reloc_hash_match): New function, extracted from..
	(ppc64_elf_tls_optimize): ..here.
	(ppc64_elf_relocate_section): Properly set addends when optimizing
	tls sequences.  Avoid unnecessary reading and writing of insns.
	Only redo reloc when symbol changed.  Bypass symbol checks when
	using tlsld_got.
	* elf32-ppc.c (ppc_elf_tls_setup): Correct comment.
	(branch_reloc_hash_match): New function, extracted from..
	(ppc_elf_tls_optimize): ..here.
	(ppc_elf_relocate_section): Avoid unnecessary reading of insns.
	Don't clear addend on zapped __tls_get_addr reloc.
