During initalization store the number type in the CFInfo bitfield in the
same way that CFNumberCreate does.
NSNumber/CFNumber stores its value in a UInt64 (_pad) with associated type
information as part of the CFInfo bitfield. NSNUmber Initialization is
performed through _CFNumberInit which copies the value bytes into _pad but
does not store the type information. This leads to broken behaviour when
converting between type repesentations. i.e. Double -> NSNumber ->
Integer.
