ada: Fix comments for recently added SPARK aspects
Implementation of contract Subprogram_Variant and Exceptional_Cases was
based on the existing code for Contract_Cases, i.e. on the existing
occurrences of Aspect_Contract_Cases, Name_Contract_Cases and
Pragma_Contract_Cases. However, occurrences of "Contract_Cases" itself
in the comments were not updated.
