This involves a few main pieces: - Add code to the GN scripts to generate DDC's patched SDK and then compile it to summaries and JS in the build output directory. - Add support to the underlying DDC build scripts to support controlling which files are built where. - Update test.dart to use the DDC SDK from the build directory. - Update create_sdk to use the built SDK instead of the checked in one. - Fix various internal DDC tools to build their own copy of the SDK (since they can't easily find the one in the build directory because it's path if config-specific) and use those. - Delete the checked DDC SDK JS and summaries. I think I got everything working. The built Dart SDK looks fine -- it's identical to one built using the old build scripts. The various tools and DDC's little test runner I *think* work, but there may be a bug or two in there. I tried the various things I could and it seems like they work but it's hard to tell since they may be kind of broken right now anyway.
