BIT opcode not lifted correctly

[samrussell]

need to set H, unset N, and set Z based on the bit, can probably just change the op that is appended:

    elif decoded.op == OP.BIT:
        assert oper_type == OPER_TYPE.IMM
        assert oper_val >= 0 and oper_val <= 7
        mask = il.const(1, 1<<oper_val)
        operand = operand_to_il(operb_type, operb_val, il, 1)
-         il.append(il.and_expr(1, operand, mask, flags='*'))
+         il.append(il.and_expr(1, operand, mask, flags='z'))

and then manually set the other 2 flags
