	* config/tc-i386.c (object_64bit): New.
	(i386_target_format): Initialize it.
	(output_disp): Use object_64bit for relocation type determination.
	(output_imm): Likewise.
	(i386_validate_fix): Likewise.
	(tc_gen_reloc): Likewise.
	(lex_got): Likewise. Remove static mode_name. Change array size
	of gotrel's rel field, and adjust its initializer. Adjust diagnostic.
	(x86_cons): Use object_64bit for deciding whether quad fields can
	have relocations.

	* gas/i386/mixed-mode-reloc.s, gas/i386/mixed-mode-reloc32.d,
	gas/i386/mixed-mode-reloc64.d: New.
	* gas/i386/i386.exp: Run new tests.
