[Ada] Eliminate early roundoff error for Long_Long_Float on x86

gcc/ada/

* libgnat/s-valrea.adb (Fast2Sum): New function.
(Integer_to_Real): Use it in an iterated addition with exact
error handling for the case where an extra digit is needed.
Move local variable now only used in the exponentiation case.
