x64 BinaryOpStub::GenerateSmiCode use wrong registers in one code path.
e.g. d8 --trace_ic
var dd = new Float64Array(2);
dd[1] = 1;
(function fn() {
for (var i = 0; i < 1000; i++)
dd[0] = 2 / dd[1];
})();
It keeps falling into runtime call and patching.
No regression test, because I don't how to test it.
