[debuginfo-tests] r318435 - Resubmit "Refactor debuginfo-tests"

All I need to reproduce is running the test twice. If I can repro that on
Linux I can probably find the cause of that. Anyway, give me 10 minutes to
try to repro the double test run on Linux. After that I'll revert if I
can't repro or the fix is not trivial.
