No difference, -fvar-tracking is disabled at -O0, so either
-fvar-tracking-assignments gets disabled as well with a warning (as in
the vta patchset I posted before) or it produces and maintains the
annotations and discards them where vartrack would have turned them into
(the implementation of your suggestion in that regard)
