weakref proposal update

This is just a heads up that the WeakRefs *presentation* has been updated
with the improved API and semantics, based on various issues and
discussions from the first version of the proposal.  The new version is
updated in place and is still at:

https://github.com/tc39/proposal-weakrefs/blob/master/specs/Weak%20References%20for%20EcmaScript.pdf

The update for the proposal document itself is still in progress. I will
reply here when it is updated (this week).

Thank you to all the people who posted issues and examples and participated
in those discussions.

We got another round of insurmountably good feedback, so I revised the
presentation again and am back to writing spec text.

I will get the revised spectext out before finishing the revision of the
accompanying proposal doc, which is primarily background and explanation.

A first round of spec-text is now pushed for the new APIs at
https://github.com/tc39/proposal-weakrefs/blob/master/specs/spec.md.

A note on the API change in the last presentation: it looks larger than it
appears.

1) Some of WeakRef was pushed in to a new parent, "WeakCell", so that it
could better support long terms in wasm, and because there's now two types,
2) WeakRefGroup was renamed to WeakFactory.

WeakRef is unchanged (and creation still preserves the Target until the end
of turn). The new "WeakCell" is for finalization only, so it doesn't have a
deref() *and* creation does not strongly preserve the Target until the end
of the turn.

er, by "it looks larger than it appears" I meant "it's smaller than it
appears" or "it looks much larger than it is" or some such :).
