INT 04 - CPU-generated - INTO DETECTED OVERFLOW

Desc:	the INTO instruction will generate this interrupt if OF (Overflow Flag)
	  is set; otherwise, INTO is effectively a NOP
Note:	may be used for convenient overflow testing (to prevent errors from
	  propagating) instead of JO or a JNO/JMP combination
