* elf-bfd.h (eh_cie_fde): Add personality_offset and
	make_per_encoding_relative to the CIE structure.  Add a padding field.
	* elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Use 0x70
	rather than 0xf0 when masking out the base address encoding
	Record the offset of personality data from the start of the CIE.
	Remove a repeated elf_backend_can_make_relative_eh_frame check.
	(find_merged_cie): Take an info argument.  If the personality
	binds locally, try converting an absolute personality into
	a local one.
	(_bfd_elf_discard_section_eh_frame): Use 0x70 rather than 0xf0
	when masking out the base address encoding.  Update the call to
	find_merged_cie.
	(_bfd_elf_eh_frame_section_offset): Discard relocations against
	the personality data if we are converting into PC-relative form.
	(_bfd_elf_write_section_eh_frame): Use 0x70 rather than 0xf0
	when masking out the base address encoding.  Handle
	make_per_encoding_relative.
