Subject: [Ada] Put back change in s-arit64.adb

Tested on x86-linux, committed on mainline.

Put back change that got removed accidentally by previous check-in.
This change fixed the failure of Double_Divide to properly detect overflow
in the case where the largest negative number is divided by minus one.

	* s-arit64.adb (Double_Divide): Put back changes that got accidentally
	removed during the previous update (test properly for case of dividing
	largest negative number by -1, which generates overflow).
