Remove _bfd_dwarf2_find_nearest_line addr_size parameter

This parameter might appear to be used to set up offset_size, but
since git commit 024b2372f5 offset_size is either set from the
debug_info data or is set to 4.

	* dwarf2.c (_bfd_dwarf2_find_nearest_line): Remove addr_size parameter.
	* libbfd-in.h  (_bfd_dwarf2_find_nearest_line): Update prototype.
	* coffgen.c (coff_find_nearest_line_with_names): Adjust
	_bfd_dwarf2_find_nearest_line calls.
	* elf.c (_bfd_elf_find_nearest_line, _bfd_elf_find_line): Likewise.
	* elf32-arm.c (elf32_arm_find_nearest_line): Likewise.
	* elf64-alpha.c (elf64_alpha_find_nearest_line): Likewise.
	* elfnn-aarch64.c (elfNN_aarch64_find_nearest_line): Likewise.
	* elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Likewise.
	* mach-o.c (bfd_mach_o_find_nearest_line): Likewise.
	* libbfd.h: Regenerate.
