	Get_Index_Bounds.

	* gnat1drv.adb: minor fix of unbalanced parens in comment
	* lib-xref.ads (Traverse_Compilation_Unit): declaration moved
	to visible part of the package to allow re-use in GNATprove.
	* lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
	from repeated code of Traverse_Compilation_Unit.
	(Traverse_Declaration_Or_Statement): fixed detection of
	generic subprograms and packages; also, iteration over case
	statement alternatives rewritten to avoid testing if the first
	alternative is present (since it must be present due to Ada
	syntax restrictions).
