Refactor our NaN boxing to be more efficient
* Use a unified way to store all Managed objects inside
a Value, instead of distinguishing between strings
and other objects.
* On 64 bit we store pointers as pointers, so accessing them
through Scoped<> objects is cheap. This implies that doubles
are now stored in a mangled form (xor'ed with a mask).
