All the compiler valhalla tests are executed with different flag combinations of
ValueTypePassFieldsAsArgs and ValueTypeReturnedAsFields. If they pass, you should have some
reasonable coverage.

FYI, I'm working on JDK-8215559 which will introduce new entry points and change all the related
code code a lot (refactoring/cleanups/bug fixes). My patch is not yet stable but I expect it to be
ready by the end of this week. It might be worth holding off on your side until this is in.

Best regards,
Tobias
