	BFD_RELOC_X86_64_GOTPC64, BFD_RELOC_X86_64_GOTPLT64,
	BFD_RELOC_X86_64_PLTOFF64.
	* bfd-in2.h: Regenerated.
	* libbfd.h: Regenerated.
	* elf64-x86-64.c (x86_64_elf_howto_table): Correct comment.
	Add howtos for above relocs.
	(x86_64_reloc_map): Add mappings for new relocs.

	R_X86_64_GOTPLT64 need a got entry.  R_X86_64_GOTPLT64 also a PLT
	entry.  R_X86_64_GOTPC64 needs a .got section.  R_X86_64_PLTOFF64
	needs a PLT entry.
	(elf64_x86_64_gc_sweep_hook): Reflect changes from
	elf64_x86_64_check_relocs for the new relocs.
	(elf64_x86_64_relocate_section): Handle new relocs.

gas/ChangeLog:
	* config/tc-i386.c (type_names): Correct placement of 'static'.

	(lex_got): Recognize @PLTOFF and @GOTPLT.  Make @GOT accept also
	Imm64.
