%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

After fixing the memory barrier for maps (https://codereview.chromium.org/1714513003), we are using a temp register for the map case. The temp register should not be aliased with the stored value (otherwise we perform the mem barrier check with a wrong value). This CL makes sure it is not aliased.
