cmd/compile: implement some moves using non-overlapping reads&writes
For moves >8,<16 bytes, do a move using non-overlapping loads/stores
if it would require no more instructions.
This helps a bit with the case when the move is from a static
constant, because then the code to materialize the value being moved
is smaller.
