* 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.
