games/mix: fix implementation of MOVE instruction (thanks nicolagi)
Plan 9 memcpy(2) uses the same implementation as memmove(2) to handle
overlapping ranges. Hovewer, the MIX MOVE instruction, as described
in TAOCP, specifically does not do this. It copies words one at a
time starting from the lowest address.
This change also expands the address validation to check that all
addresses within the source and destination ranges are valid before
proceeding.
