           Summary: [Custom]: Element upgrade algorithm needs to be
                    rewritten

The last iteration of the algorithm mutates the DOM tree (see bug 20490) and
has  terminology issues (see bug 20489).

Given that in bug 20913 we're converging on the decision that guarantees that
the platform object of a custom element is always instantiated properly, we can
avoid DOM mutation and instead only update prototype chains when upgrading.
