[COMMITTED] ada: Fix incorrect handling of Aggregate aspect

[Marc Poulhiès]

This change fixes 2 incorrect handlings of the aspect.
The arguments are now correctly resolved and the aspect is rejected on
non array types.

gcc/ada/

	* sem_ch13.adb (Analyze_One_Aspect): Mark Aggregate aspect as
	needing delayed resolution and reject the aspect on non-array
	type.

Tested on x86_64-pc-linux-gnu, committed on master.
