[Ada] 'others' in conditional_expressions

2019-10-10  Bob Duff  <duff@adacore.com>

gcc/ada/

	* sem_aggr.adb (Resolve_Aggregate): Add missing cases in the
	Others_Allowed => True case -- N_Case_Expression_Alternative and
	N_If_Expression.  Use Nkind_In.
	* atree.adb, atree.ads, sinfo.adb, sinfo.ads (Nkind_In): New
	16-parameter version.

-       * sem_aggr.adb (Resolve_Array_Aggregate): Set properly the
-       Predicated_Parent link of an itype created for an aggregate, so
-       that the predicate_function of the parent can support proofs on
-       the object that it initializes.
