ada: Update annotations in runtime for proof
With bump of stable SPARK used for proof of the runtime,
some annotations need to change.
gcc/ada/
* libgnat/s-aridou.adb (Scaled_Divide): Add assertions.
* libgnat/s-valuti.adb: Add Loop_Variant.
* libgnat/s-valuti.ads: Add Exceptional_Cases on No_Return
procedure.
