the subprogram call is expanded, if the interface has a secondary
dispatch table the expander will add a type conversion to force
the displacement of the pointer.
(Resolve_Call): If a function that returns an unconstrained type is
marked Inlined_Always and inlined, the call will be inlined and does
not require the creation of a transient scope.
