Source/JavaScriptCore/JavaScriptCore.xcodeproj/project.pbxproj change should probably be reverted?

> *this = JSValue(reinterpret_cast<JSCell*>(activation));

These casts are all incorrect, they should be static_casts (reinterpret_cast is almost always the wrong cast when casting within a class hierarchy).
But can't you just delete all these overloaded= operators? - why doesn't the compiler just call the operator=(JSValue) automatically?

If we're going to access the two halves of the value like we do in JSVALUE32_64 it seems like we should have the IntValueDescriptor defined in JSValue, where it is for JSVALUE32_64 (better still, unify the two!)

r- for the reinterpreting.

It seems like this change caused a Windows build failure:

The commit queue is broken and needs to be disabled.  I'll re-land on monday with the windows fix.
