Ref: A smart pointer for the reference age.
<https://webkit.org/b/120570>
Reviewed by Antti Koivisto.
Source/WebCore:
Use Ref<T> for various stack guards where null checking isn't needed.
Source/WTF:
Add a very simple simple Ref<T> smart pointer class that is never null.
It's initialized by passing a T& to the constructor and cannot be assigned to.
operator-> is not overloaded, to prevent unsafe-looking code.
The value is extracted by "T& get()", since C++ does not let you override operator.()
