In each library where an import is removed, the library uses some elements provided by the import, BUT there is another import which provides all of the same elements, and at least one more which the library uses. In this change, we remove the imports which can be simply removed in favor of the other already present imports. See https://github.com/dart-lang/sdk/issues/44569 for more information.

The text format is currently very ad-hoc and there is no conversion back, but it's a pleasant way to view the IR.
