I think this will work. I talked with the VM team, and none of them sound like
they'd be impacted by this change.

This won't work. The original idea was as follows:

You run stuff from dart/sdk/bin to avoid building the SDK. 

You run stuff from PRODUCT_DIR/dart-sdk/bin if you want to test the SDK
(including snapshots).

The advantage to this setup is that there is no build step required to test
incremental changes to dart2js, I assume pub would benefit from this as well.
