* elf-bfd.h (struct eh_cie_fde): Add set_loc pointer.

	* elf-bfd.h (struct eh_cie_fde): Add set_loc pointer.
	* elf-eh-frame.c (skip_cfa_op): Fix handling of DW_CFA_advance_loc.
	Handle DW_CFA_{remember,restore}_state, DW_CFA_GNU_window_save,
	DW_CFA_val_{offset{,_sf},expression}.
	(skip_non_nops): Record number of DW_CFA_set_loc ops.
	(_bfd_elf_discard_section_eh_frame): Require skip_non_nops recognizes
	all ops.  If there are any DW_CFA_set_loc ops and they are pcrel
	or going to be pcrel, compute set_loc array.
	(_bfd_elf_eh_frame_section_offset): If make_relative, kill relocations
	against DW_CFA_set_loc operands.
	(_bfd_elf_write_section_eh_frame): Handle DW_CFA_set_loc adjusting.

	* ld-elf/eh4.d: New test.
	* ld-elf/eh4.s: New file.
	* ld-elf/eh4a.s: New file.
