This patch initializes the top Sloc in the scope stack, which is read in
Pop_End_Context and was previously uninitialized.

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

2013-04-12  Bob Duff  <duff@adacore.com>

	* par-ch7.adb (P_Package): Initialize Sloc in the newly-pushed scope
	stack entry.
