* sem_ch3.adb (Build_Derived_Record_Type): If the derived
type has new discriminantss that constrain inherited ones, use
the discriminant type in the original declaration to check for
conformance, because in the presence of array components with a
smaller range that are constrained by the origina discriminant,
the compiler will have created a narrower subtype for that
discriminant.
