[COMMITED] ada: Delay expansion of iterator specification in preanalysis

["Marc Poulhiès" <poulhies@adacore.com>]

From: Piotr Trojanek <trojanek@adacore.com>

When preanalysing spec expression (e.g. expression of an expression
function), the name of iterator specification should not be expanded.

This patch simplifies a complicated condition for delaying expansion
within quantified expressions and iterated component associations.

	* sem_ch5.adb (Analyze_Iterator_Specification): Delay expansion
	based on Full_Analysis flag.
