Fix for
c330001 - PR ada/19386
* decl.c:
(gnat_to_gnu_field): Do not necessarily invoke make_packable_type
on the field if Pragma Component_Alignment (Storage_Unit).
(gnat_to_gnu_entity, case object): Do not treat a renaming that has
side-effects as if it were a constant; also make SAVE_EXPR to protect
side-effects.
(gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
UNION_TYPE.
(make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
(components_to_record): Test it.
Fix improper usage of REFERENCE_CLASS_P.
* utils2.c (build_binary_op, case MODIFY_EXPRP): Treat UNION_TYPE as
RECORD_TYPE.
* utils2.c: Minor reformatting.
* utils.c (convert, case UNION_TYPE): Check TYPE_UNCHECKED_UNION;
handle other cases like RECORD_TYPE.
* utils.c (gnat_pushdecl): Set TREE_NO_WARNING.
