>+        Move WTF::generateObjectIdentifier()'s internal counter out-of-line so make sure it never gets
>+        duplicated at each call site. This has caused some hard-to-debug issues with duplicate
>+        identifiers such as Bug 193761.
>+
>+        Also move it to ObjectIdentifier and rename it to generate() as this make call sites nicer
>+        when they have a typedef for the ObjectIdentifier<T> type.
