[Ada] Do not give warnings for compiler-generated entities by default
The rationale is that these entities are almost always the result of
expansion activities in the front-end, over which the user has very
limited control. These warnings can be restored by means of -gnatD.

on the decl if Comes_From_Source is false for the associated node.
