Ada: Remove temporary Aspect_Unimplemented code.
The Ada compiler removes the temporary Aspect_Unimplemented code, which had been present since 2015.
The Ada compiler removes the Aspect_Unimplemented code, which was marked as temporary and had been in the codebase since 2015. This removes dead code from the Ada compiler.
In Details
The commit removes Aspect_Unimplemented from aspects.ads and sem_ch13.adb. This code likely served as a placeholder for handling unimplemented aspects in the Ada front end. Its removal suggests that the corresponding functionality has since been implemented or deemed unnecessary.
For Context
Modern compilers often contain experimental or incomplete features that are initially marked as temporary. This commit removes dead code related to an unimplemented aspect. Aspects in Ada provide a way to add extra information or modify the behavior of program entities.
