Henrik G. Olsson cbc0ec3b88 Add -verify-ignore-unrelated where necessary (NFC)
These are tests that fail in the next commit without this flag. This
does not add -verify-ignore-unrelated to all tests with -verify, only
the ones that would fail without it. This is NFC since this flag is
currently a no-op.
