* i386-dis.c (FWAIT_OPCODE): Define.

	* i386-dis.c (FWAIT_OPCODE): Define.
	(fetch_data): Don't print an error message if we have already
	found an fwait prefix.
	(ckprefix): Use FWAIT_OPCODE rather than 0x9b.
	(print_insn_i386): If setjmp fails, indicating a data error, but
	we have found an fwait prefix, then print it as an fwait
	instruction.  In any case, return the number of bytes consumed, if
	any, rather than always returning -1.
