When preanalysing spec expression (e.g. expression of an expression
function), the name of iterator specification within an iterated
component association should not be expanded, especially in GNATprove
mode.

gcc/ada/

	* sem_ch5.adb (Analyze_Iterator_Specification): Delay expansion of
	for iterated component association just like it is done within
	quantified expression.
