ada-tree.h (DECL_TAFT_TYPE_P): New flag.
* gcc-interface/ada-tree.h (DECL_TAFT_TYPE_P): New flag.
* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Incomplete_Type>: Set it
if this is a Taft amendment type and the full declaration is available.
* gcc-interface/trans.c (process_type): Likewise.
If there is an old type, mark the new one as used if DECL_TAFT_TYPE_P.
(process_freeze_entity): Likewise.
* gcc-interface/utils.c (dummy_global): New static variable.
(gnat_write_global_declarations): If there are types declared as used
at the global level, insert them in the global hash table.
