Fixes#10711
The `ModuleVariablesTransformer` only adds module variables in use. This
was missing module variables used by providers since we ran the provider
too late. This moves the transformer and adds a test for this.
Fixes#10680
This moves TargetsTransformer to run after the transforms that add
module variables is run. This makes targeting work across modules (test
added).
This is a bug that only exists in the new graph, but was caught by a
shadow error in #10680. Tests were added to protect against regressions.
Ensure that each instance of BasucGraphBuilder gets a name corresponding
to the Builder which created it. This allows us to differentiate the
graphs in the logs.
