Properly fixed.

68000 interrupt line (IPL) sampling seems to be microcode controlled after all because for example some MOVE.L variants fetch interrupt line state before write and some after write. (even when cycle sequence is exact same between variants after writes and only difference is effective address calculations before writes)
