Align eh_frame FDEs according to their encoding
bfd/
* elf-bfd.h (struct eh_cie_fde): Add u.cie.per_encoding_aligned8.
* elf-eh-frame.c (size_of_output_cie_fde): Don't align here.
(next_cie_fde_offset): New function.
(_bfd_elf_parse_eh_frame): Set u.cie.per_encoding_aligned8.
(_bfd_elf_discard_section_eh_frame): Align zero terminator to
four bytes. Align CIEs to four or eight bytes depending on
per_encoding_aligned8. Align FDEs according to their encoding.
Pad last FDE to output section alignment.
(_bfd_elf_write_section_eh_frame): Adjust to suit. Remove
assertion.
* elf64-ppc.c (glink_eh_frame_cie): Delete padding.
(ppc64_elf_size_stubs): Pad glink eh_frame as per elf-eh-frame.c.
(ppc64_elf_finish_dynamic_sections): Adjust to suit.
