Core2 issue

Core2 has sometimes DSZ modifier with value 180 (e.g. ADD.180, which seems to be similar to DSZ32)

Typical usage

TMP1 =         MOVE_DSZ32     (CONST         , CONST_16_00F  )
BL =           MOVE_DSZ8      (CONST         , CONST_16_0F0  )
ESP_20 =       MOVE_DSZ16     (TMPB          , ESP_20        , OA_4)
