[DataFlowSanitizer] Generate some test checks (NFC) (#161502)

Generate test checks for some dfsan tests with UTC to make them easier
to update.

For this purpose I've added a `-dfsan-add-global-name-suffix=0` option
to avoid the addition of the `.dfsan` suffix on functions, which allows
us to use normal UTC check lines. Otherwise we'd have to use
`--include-generated-funcs` instead, which produces less nice results,
as the check lines are not interleaved with the original functions
anymore.
