	PR ld/5526
	* elf-bfd.h (eh_cie_fde): Add u.cie.u.full_cie and u.cie.merged
	fields.  Rename u.cie.u.merged to u.cie.u.merged_with.
	(eh_frame_sec_info): Add a cies field.
	(eh_frame_hdr_info): Add a merge_cies field.
	* elf-eh-frame.c (cie): Add a reloc_index member to the personality
	union.
	(_bfd_elf_begin_eh_frame_parsing): Set hdr_info->merge_cies instead
	of hdr_info->cies.
	(_bfd_elf_parse_eh_frame): Remove tmp_cie.  Ccreate an array of
	cie structures in all cases and use it instead of extended_cies.
	If merging, store the cie array in sec_info->cies and point each
	CIE's eh_fde_cie at the associated element.  Do not try to
	calculate the value of the personality routine here; record the
	offset of the relocation instead.  Do not merge CIEs here.
	(_bfd_elf_end_eh_frame_parsing): Do not free hdr_info->cies here...
	(_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
	(_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
	(find_merged_cie): New function.
	(_bfd_elf_gc_mark_fdes): Use it.  Free sec_info->cies.
