Summary: This type is created on-demand and used as the base type for array ranges. Since it is "special", its construction did not go through the createTypeDIE function and so it was never inserted into the accelerator table, although it clearly belongs there. I add an explicit addAccelType call to insert it into the table. During review, we also decided to rename the type to something more unique to avoid confusion in case the user has own "sizetype" type. The new name for the type size __ARRAY_SIZE_TYPE__.
