[Ada] Compiler abort on in_out function parameter with type invariant

gcc/ada/

	* exp_ch6.adb (Add_View_Conversion_Invariants): Do not insert
	generated invariant checks when the call is a function call.
	These tests are properly inserted in the code in procedure
	Insert_Post_Call_Actions, which takes care of finding the proper
	insertion point for the checks.
	(Insert_Post_Call_Actions): Add question marks to indicate
	possible gap in handling function calls that appear as aggregate
	components.
