test_options: use testing options with (almost) real defaults.

Browse Source 
Previously, we just used options set to all 0s, but this causes some
pretty severe workarounds throughout the code, as our options fail
to validate, or count as "default" for the wrong reasons.

Note that in some places, we stop getting spurious warnings or
failures which the tests previously demanded.  In these cases, I've
changed the test behavior.

Fixes 32175.
