	* sem_ch4.adb (Try_Container_Indexing): New procedure to implement the
	general indexing aspects of Ada2012. Called when analyzing indexed
	components when other interpretations fail.
	* sem_ch8.adb (Find_Direct_Name): check for implicit dereference only
	in an expression context where overloading is meaningful. This excludes
	the occurrence in an aspect specification (efficiency only).

	related to iterators can be set by an attribute specification, but
	cannot be queried.
	* sem_ch13.adb (Analyze_Aspect_Specifications): handle
	Constant_Indexing and Variable_Indexing.
	(Check_Indexing_Functions): New procedure to perform legality checks.
	Additional semantic checks at end of declarations.
