The point of the test is that GCC calls the vector(initializer_list<T>)
constructor (which I deleted so that we get an error if it's used, i.e. it
wasn't meant to be a runtime test, just compile-time).

I thought that v{std::move(v)} should have called the vector move constructor,
but actually https://wg21.link/cwg2137 says that GCC is right here (and Clang
and EDG don't implement that DR yet, in Clang's case because it was found to
create other problems).

But GCC seems to be doing the right thing here.
