In principle this looks good, there's no other need to pass all these references around, we just need the "entry values enabled" bit. The test failures on CI are consistent with something going wrong though, the fragment of output from dbginfo-entryvals.mir shows no entry-values are generated but the test expects to see them. It's not immediately clear to me where the information goes missing.
