  [OpenMP] Use Attributor to find underlying objects of stores

When we see a store in generic mode we need to decide if we should guard
it for SPMDzation. This patch changes the getUnderlyingObjects call to
the more optimistic getAssumedUnderlyingObjects call to identify more
thread local pointers.
