1569         If merging, store the cie array in sec_info->cies and point each
1570         CIE's eh_fde_cie at the associated element.  Do not try to
1571         calculate the value of the personality routine here; record the
1572         offset of the relocation instead.  Do not merge CIEs here.

1574         (_bfd_elf_discard_section_eh_frame_hdr): ...do it here instead.
1575         (_bfd_elf_gc_mark_fdes): Mark the original (unmerged) CIE.
1576         (find_merged_cie): New function.
1577         (_bfd_elf_gc_mark_fdes): Use it.  Free sec_info->cies.
