// A StrongInt<T> with a NullStrongIntValidator should compile away to a raw T
// in optimized mode. What this means is that the generated assembly for:
//
// int64 foo = 123;
// int64 bar = 456;
// int64 baz = foo + bar;
// constexpr int64 fubar = 789;
// int64_t foo = 123;
// int64_t bar = 456;
// int64_t baz = foo + bar;
// constexpr int64_t fubar = 789;
//
// ...should be identical to the generated assembly for:
//
// DEFINE_STRONG_INT_TYPE(MyStrongInt, int64);
// DEFINE_STRONG_INT_TYPE(MyStrongInt, int64_t);
// MyStrongInt foo(123);
// MyStrongInt bar(456);
// MyStrongInt baz = foo + bar;
