Current optimization use only splits to transform arithmetic into lea and vice
versa. It does not work for move because corresponding lea template will be
equal. We can check if lea is required during instruction emit.
I have a patch to fix it. Bootstrap and make check passed. I'm currently
checking performance changes.
