Unify DDC SDK with Dart repo's SDK

[jmesserly]

DDC compiles against the Dart SDK that is installed, but runs against an older built snapshot from our implementation. Now that we're in the same repository, we should be able to handle this in the patch_sdk script.

I'll take dart:async.

@jacob314 will look at dart:html once dart:async is landed

dart:async is done as of 8154650779ea579e4d599ad422e459305b405eac

Working on Uri and probably dart:convert (since Uri uses it) now.

OK, Uri and dart:convert are landed, though @floitschG says there may be some more dart:convert changes coming soon after. What's left to do?

This issue was originally about unforking DDC's SDK but we've been using it to refer to rolling it. To disambiguate, I'm forking the bug. This one is now about unforking. The bug for just rolling the latest SDK is #565.

[jmesserly]

I investigated DDC summary. We can produce it with new Analyzers, but we can't build tests against it because some packages and a few tests seem to depend on dart:io (not sure if they use much of it or what's up there).

[jmesserly]

this should be way easier nowadays because we're in the same repo

here's one SDK fix: https://codereview.chromium.org/2718643003/

[jmesserly]

okay current list of problems.

Bob's CL here needs to be redone 20e402c

lots of typing problems with dart:convert, in particular "startChunkedConversion" and "bind"

need to copy over a workaround for unsound typing in ListMixin.sort (we already have this workaround in JSArray.sort)

copied over some more things from dart2js impl code (this will be in my CL)

[jmesserly]

another SDK fix https://codereview.chromium.org/2715833004/

[jmesserly]

fixed with fe294f3 ... I'll open a new one for tracking the html libraries

[jmesserly]
