The pass to transform gimple based on value profiling runs with autofdo
on, but currently every transformation fails. For indirect calls autofdo
does it on its own, and it doesn't suppport other value profiling. So don't
run this pass when autofdo is active. This also avoids bogus
dump file entries.

I don't think that comment is really correct. There's all kinds of
things going on with div/mod operations, turning string builtins into
straightline code, etc that I see in value-prof that aren't done by
autofdo AFAICT.
I can live with the change if the comment is corrected.
