	bypasses all processing when the iteration scheme is related to a
	QE. Relovate the code which analyzes loop parameter specifications
	to a separate routine.	(Analyze_Iterator_Specification):

	procedure allows for a stand-alone analysis of a loop parameter
	specification without the need of a parent iteration scheme. Add

	Ignore any loop scopes generated for QEs when detecting an expression
	function as the scopes are cosmetic and do not appear in the tree.
	(Resolve_Quantified_Expression): Removed. All resolution of
	QE constituents is now performed during analysis. This ensures
	that loop variables appearing in array aggregates are properly
	resolved.

2012-04-02  Ed Schonberg  <schonberg@adacore.com>
