[COMMITTED] ada: Remove unreferenced utility routine Get_Logical_Line_Number_Img

["Marc Poulhiès" <poulhies@adacore.com>]

From: Piotr Trojanek <trojanek@adacore.com>

Routine Get_Logical_Line_Number_Img was introduced for splitting of
Pre/Post contracts, but subsequent patch for that feature removed its
only use. It was then used by GNATprove, but that use is now removed
as well.

gcc/ada/

	* sinput.adb, sinput.ads (Get_Logical_Line_Number_Img): Remove.

Tested on x86_64-pc-linux-gnu, committed on master.
