Fixup bad commit

Revert "wip";  This reverts commit 81f05377583c8a13b03c2449a4faf15e9bc91ce8.
The patch from another incomplete branch got committed with  a correct patch for PR #636

Rename AttachReferrerNameTransformer to AttachModuleNameTransformer.
This should have been in PR #636; I don't know how it was not.
