If you don't like this v4, let me know and then I can go back memcpy
for next 
version. 

Just open code the whole copy. It should be easy really. As I said, you
have the src and dst already in registers and you know they are aligned,
so just put the size of the frame in a register (divided by 4), do an
mtctr and do a little load_update/store_update loop to do the copy, all
in the asm.
