Do we want to type std::experimental::variant every time we use this in WebKit, or do we want to put this line in the header?

I think for now we want to type it. As I start using it, if it becomes annoying, I will consider adding something like:

namespace WTF {

template<typename ... Types>
using Variant = std::experimental::variant<Types>;

}

But I want to see first.
