Implicitly generated postcondition procedures are now marked as requiring
debug info, for improved support for decision coverage analysis.

No simple test available.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Set Debug_Info_Needed
	on the entity of an implicitly generated postcondition procedure.
