  Log Message:
  -----------
  [Attributor][NFCI] Use queries without exclusion set whenever possible

If a query uses an exclusion set but we haven't used it to determine the
result, we can cache the query without exclusion set too. When we lookup
a cached result we can check for the non-exclusion set version first.

  [Attributor][NFCI] Avoid AAIntraFnReachability updates if possible

Even if liveness changed, we only care about certain dead edges in
AAIntraFnReachability. If those are still dead, we can avoid an update.
