add_local_tls_pair): New functions.
	(Output_data_got::add_local_pair_with_rel): Remove second
	reloc param.  Expand comment.
	(Output_data_got::Got_entry): Rename use_plt_offset_ to
	use_plt_or_tls_offset_, similarly for constructor param.
	(Output_data_got::Got_entry::write): Add got_index param.
	* output.cc (Output_data_got::add_global_tls, add_local_tls,
	add_local_tls_pair): New functions.
	(Output_data_got::Got_entry::write): Handle tls symbols
	with use_plt_or_tls_offset_ set specially.
	(Output_data_got::add_local_pair_with_rel): Only one reloc.
	(Output_data_got::do_write): Replace iterator with index, pass
	index to entry write function.
	* target.h (Target::tls_offset_for_local, tls_offset_for_global,
	do_tls_offset_for_local, do_tls_offset_for_global): New functions.
	* arm.cc (Target_arm::Scan::local): Update add_local_pair_with_rel
	call.
	* i386.cc (Target_i386::Scan::local): Likewise.
	* sparc.cc (Target_sparc::Scan::local): Likewise.
	* x86_64.cc (Target_x86_64::Scan::local): Likewise.
	* powerpc.cc (Target_powerpc::do_tls_offset_for_local,
	do_tls_offset_for_global): New functions.
	(Target_powerpc::Scan::local): Correct TLS relocations and got
	entry values.
	(Target_powerpc::Scan::global): Don't emit unnecessary
	dynamic relocations on TLS GOT entries.
