discriminant values.

check individual components withing a variant.

* sem_ch12.adb (Instantiate_Type): Add condition to detect the correct
pass of Unchecked_Union subtypes as generic actuals to formal types
that lack known_discriminant_parts or that are derived Unchecked_Union
types, and do nothing. In any other case, produce an error message.

* sem_ch3.adb (Analyze_Component_Declaration): Add function
Contains_POC. It determines whether a constraint uses the discriminant
of an enclosing record type.

appropriate flag.
(Derived_Type_Declaration): Remove guard that prevents derivation from
Unchecked_Union types.
(Process_Subtype): Remove quard that prevents the creation of Unchecked_
Union subtypes.

references to Unchecked_Union discriminants.

* sem_ch6.adb (Create_Extra_Formals): Add condition to skip extra
formal generation when dealing with Unchecked_Unions.
(Set_Actual_Subtypes): Add condition to prevent generation of actual
subtypes for Unchecked_Unions.
