515 to Original_Aspect_Name. Pragmas Contract_Cases, Depends,
516 Extensions_Visible, Global, Postcondition, Precondition and
517 Test_Case now carry generic templates when the related context
518 is a generic subprogram. The same pragmas are no longer
519 forcefully fully analyzed when the context is a subprogram
520 that acts as a compilation unit. Pragmas Abstract_State,
521 Initial_Condition, Initializes and Refined_State have been clean
522 up. Pragmas Post, Post_Class, Postcondition, Pre, Pre_Class
523 and Precondition now use the same routine for analysis. Pragma
524 Refined_Post does not need to check the use of 'Result or
525 the lack of a post-state in its expression. Reimplement the
526 analysis of pragma Test_Case.

583 2015-03-02 Ed Schonberg <schonberg@adacore.com>
585 * sem_ch8.adb (Available_Subtype): Optimization in
586 Find_Selected_Component: when safe, use existing subtype of
587 array component, possibly discriminant-dependent, rather than
588 creating new subtype declaration for it. In this fashion different
589 occurrences of the component have the same subtype, rather than
590 just equivalent ones. Simplifies value tracing in GNATProve.

1018 on type entities, to enforce AI12-0133: default initialization

1022 * sem_ch3.adb (Find_Type_Name); Set new flag
1023 Partial_View_Has_Unknown_Discr when needed.
