I have something different to propose. We currently didn't have any 
instruction to load chunk after the 64 bits. Currently we use the shifter to 
do this and in fact it's not a good idea, if we want to write evolutive code.

An idea is to propose a loadchunk that work like loadcons, but with every
chunk size. With this we are scalable as much as we want and we can do 
what we want with any registers size. And if we add this instruction, the
loadconsp will be seen like a immediate form of loadchunk.

So what about this idea ?
