Use twoPtrValue in stead of ptrAndLongRep for implementation of some internal Obj types. On most platforms this doesn't make a difference,

as (void *) and (long) generially have the same size. The only exception where it makes a difference is win64, as we can now store 64 bits in this field in stead of only 32 bits, exactly what the processor is optimized for.
