It looks inconsistent that setObjectGroup is a method of WrapperTypeInfo whereas
setWrapperReferenceFrom is a method of DOMDataStore.

[kouhei (in TOK), 2013/10/17 02:30:09]

setObjectGroup is not a method of WrapperTypeInfo. It's a WebCore:: global
function. I placed it here because it doesn't touch wrapper internals and
because I need to use it as a default implementation of
resolveWrapperReachability in WrapperTypeInfo.h.

[haraken, 2013/10/17 03:28:22]

I still think these methods are misplaced, but it's OK for now. We have to allow
the mis-placement in order to encapsulate UnsafePersistent.

Let's clean up these methods when removing UnsafePersistent.
