[OpenMP][FIX] Be more deliberate about invalidating the AAKernelInfo state

This patch fixes a problem when the AAKernelInfo state was invalidated,
e.g., due to `optnone` for a kernel, but not all parts indicated the
invalidation properly. We further eliminate most full state
invalidations as they should never be necessary.
