testcase extracted from test/SemaCXX/cxx2a-destroying-delete.cpp from the clang
8.0.0 test suite w/ -std=c++17:
namespace std {
using size_t = decltype(sizeof(0));
enum class align_val_t : size_t;
struct destroying_delete_t { };
}
struct A {
void operator delete(A*, std::destroying_delete_t, std::align_val_t);
void operator delete(A*, std::destroying_delete_t, std::size_t,
std::align_val_t);
