ada: Fix assertion failure on prefixed call with access to class-wide interface

The assertion failure shows that the 'Access reference implicitly introduced
for calls written in object notation whose controlling first parameter is an
access to class-wide interface is not later expanded in the cases where the
pointer to the interface needs to be retrieved.

gcc/ada/ChangeLog:

	PR ada/34290
	* sem_ch4.adb (Try_Object_Operation.Complete_Object_Operation): Call
	Preserve_Comes_From_Source to preserve the flag on nodes.  Relocate
	the Obj node consistently.  Preserve the Comes_From_Source flag for
	the case of an implicit 'Access reference and post the local errors
	on the rewritten prefix consistently.
	* sem_util.adb (Is_Aliased_View): Also return true for a generalized
	reference to the result of a function call.
