Edit .eh_frame symbols
Experimental support for moving symbols defined in .eh_frame as their
CIEs/FDEs are edited or merged.
* elf-bfd.h (struct eh_cie_fde): Add aug_str_len and aug_data_len.
(_bfd_elf_adjust_eh_frame_global_symbol): Declare.
* elf-eh-frame.c (_bfd_elf_parse_eh_frame): Set aug_str_len and
aug_data_len.
(offset_adjust): New function.
(_bfd_elf_adjust_eh_frame_global_symbol): Likewise.
(adjust_eh_frame_local_symbols): Likewise.
(_bfd_elf_discard_section_eh_frame): Call adjust_eh_frame_local_symbols
after changing anything. Return true if anything changed.
* elflink.c (bfd_elf_discard_info): If .eh_frame changed, call
_bfd_elf_adjust_eh_frame_global_symbol for globals.
