This adds a pkg/compiler_unsupported directory to the repo and puts the basic
package artifacts in it. It's a manual process to run the tool/create_library.py
script to copy the dart2js source code into the lib/ directory. This copy of the
source is excluded from the repo via git and svn ignores.

Another option is to keep this skeleton for a compiler_unsupported package in
github. The compiler_unsupported package will hopefully for fairly short-lived,
so keeping it outside of the svn repo wouldn't have any real negative impact.

LGTM.
I'm surprised you don't need the lib-directory, though.

Historical note: we had code in tools/publish_pkg.py to publish
compiler_unsupported, but it was dead code so removed in this CL:

fwiw, I like your approach better (in this CL), less code generation is good...

not a great page either, but maybe a bit more useful:

As far as I know, the sdk/lib/_internal/lib directory is only used by dart2js at
runtime, but is not actually part of the application source.

Each embedder currently needs to solve the problem of problem of making the SDK
available to dart2js. I believe Peter's creating a String from the SDK as part
of a build process; I'm creating a big ~tar ball containing all the dart SDK
sources.

That one is a little long for my taste. I tried a goo.gl shortened one but it
didn't look right. I think dartlang.org is close enough.
