The problem is that by the time at the end of cp_parser_simple_declaration we
call check_tag_decl (via shadow_tag), which is supposed to check that the
simple declaration is valid, we already called finish_decltype_type thus it
doesn't see the decltype, it sees something like:
void foo() { struct A; }
a valid simple declaration.
