[Ada] Prove double precision integer arithmetic unit
gcc/ada/
* libgnat/a-nbnbig.ads: Mark the unit as Pure.
* libgnat/s-aridou.adb: Add contracts and ghost code for proof.
(Scaled_Divide): Reorder operations and use of temporaries in
two places to facilitate proof.
* libgnat/s-aridou.ads: Add full functional contracts.
* libgnat/s-arit64.adb: Mark in SPARK.
* libgnat/s-arit64.ads: Add contracts similar to those from
s-aridou.ads.
* rtsfind.ads: Document the limitation that runtime units
loading does not work for private with-clauses.
