Fixes an internal compiler error in the D compiler that occurred when a forward reference to a nested struct changed the type mode of its enclosing struct. The fix involves setting TREE_ADDRESSABLE early and moving mode setting and propagation to finish_aggregate_mode and finish_aggregate_type, respectively.
