Fix test broken by r304020

It's a workaround because the test was flakey passing to begin with, but
it looks like (going off commit history) it really did want to test in
the presence of debug info, so keep that behavior (by adding something
to the CU so it's not dropped) & restore the flakey pass in the process.
(added a FIXME in case someone else decides to look at it later)
