	(_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.
