[Ada] Fix expansion of aggregate for discriminated limited extension
The presence of the discriminants prevents the values associated with the
components of the parent type from being put into the sub-aggregate built
for the _Parent component.
gcc/ada/
* exp_aggr.adb (Expand_Record_Aggregate.Build_Back_End_Aggregate):
Skip the discriminants at the start of the component list before
looking for the components inherited from the parent in the case
of a tagged extension.
