* config/tc-z8k.c (parse_reg): Invalid registers generate an error

Browse Source 
now, not only a warning.  Add some more checks to detect invalid
	registers.
	(get_operand): For CLASS_IR remember register size in mode struct.
	(get_specific): Handle new CLASS_IRO type.  Add register size
	checks for CLASS_IR and CLASS_IRO.
        (md_apply_fix3): Fix undefined usage of buf.
