Today to invoke Dart2js with sequential actions there are 2 ways to specify the stage from the command line. By specifying a `write-<stage-data>=<some-uri>` or by using `stage=<some-stage>`. Internally we use the former via a similar (but separate) concept to Dart2jsStage. The goal here is to consolidate all these different entry points.
The new CLI works as follows:
- To run the compiler in full you can:
- Pass no additional flags as before
- Specify 'stage=all'
- 'dump-info-all' runs the full compilation from scratch but includes
dump info.
- To run the compiler in sequential mode you specify a stage:
- Each stage has its own name passed to the '--stage' flag.
- All the intermediate data URIs can be passed to every stage and only
the relevant ones are used for any given stage. If no URI is passed
then a default URI is used.
- 'dump-info' is now its own stage. Partial dump info data is
always included in the emit-js and codegen-emit-js steps.
- 'cfe-only' flag is maintained for compatibility with Flutter CLI.
