Optimize Object.seal and Object.preventExtensions They both now run fast (due to utilizing transitions instead of always creating new maps) and sealed or non-extensible objects can stay in fast mode after transitioning. This almost entirely reuses the code for transitioning objects frozen by Object.freeze(), with the added benefit of freeing up a bit on the map (we no longer keep track of frozen-ness, as that bit wasn't used for anything interesting).
