[CLASSES]: Add a ->declaration member to struct class 

For cases where the compiler doesn't emits the whole struct definition for
things like base classes that don't have any of its members acessed, just the
ones in its descendants.

Will be used to avoid emiting hole anottations, since we don't have the
size of these classes we can't say if its smaller than the space allocated
by the compiler.
