[webkit-dev] Stop Using Raw Pointers & References in New Code

[Michael Catanzaro]

Hm, I see you're right because CheckedRef/CheckedPtr are intrusive 
pointers that require modification of the type to be pointed to, so 
they are not going to work in general as they cannot be used for types 
that do not inherit from CanMakeCheckedRef/CanMakeCheckedPtr.
