ada: Rewrite Set_Image_*_Unsigned routines to remove recursion.

This rewriting removes algorithm inefficiencies due to unnecessary
recursion and copying. The new version has much smaller and statically known
stack requirements and is additionally up to 2x faster.

gcc/ada/

* libgnat/s-imageb.adb (Set_Image_Based_Unsigned): Rewritten.
* libgnat/s-imagew.adb (Set_Image_Width_Unsigned): Likewise.
