ensure that what we reference is indeed stabilized instead of relying
on assumptions on what the stabilizer does.
(gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
type imported through a limited_with clause, use its non-limited view.
(Has_Stdcall_Convention): New macro, to centralize the Windows vs others

and to let the caller know if the stabilization has succeeded.
(gnat_stabilize_reference): Now a simple wrapper around
maybe_stabilize, for common uses without restriction on lvalues and
without need to check for the success indication.

generation and we are at the top level, check for a potential violation
