[COMMITTED] ada: Fix error on SPARK_Mode on library-level separate body

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

From: Yannick Moy <moy@adacore.com>

When applying explicitly SPARK_Mode on a separate library-level spec
and body for which a contract needs to be checked, compilation with
-gnata was failing on a spurious error related to SPARK_Mode
placement. Now fixed.

gcc/ada/

	* sem_prag.adb (Analyze_Pragma): Add special case for the special
	local subprogram created for contracts.

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