Use GC critical section for profile saver
Since visit classes uses DecodeWeakGlobal, it may block on decoding
weak globals. This can cause deadlocks since it will be blocked while
holding the classlinker classes lock.
Using a GC critical section ensures that the GC is not running while
we visit the classes for the profile saver.
I didn't put the logic in the VisitClasses call since some of the
callers already have no thread suspension checks that would fail from
this.
