abd242a908 Fix sparc TLS call relaxation when the delay slot sets up %o0.
bfd/

	PR binutils/13301
	* elfxx-sparc.c (sparc_elf_find_reloc_at_ofs): New function.
	(_bfd_sparc_elf_relocate_section): Always move the __tls_get_addr
	call delay slot instruction forward 4 bytes when performing
	relaxation.

gold/

	PR binutils/13301
	* sparc.cc (Target_sparc::Relocate::reloc_adjust_addr_): New
	member to track relocation locations that have moved during TLS
	reloc optimizations.
	(Target_sparc::Relocate::Relocate): Initialize to NULL.
	(Target_sparc::Relocate::relocate): Adjust view down by 4
	bytes if it matches reloc_adjust_addr_.
	(Target_sparc::Relocate::relocate_tls): Always move the
	__tls_get_addr call delay slot instruction forward 4 bytes when
	performing relaxation.
