  -----------
  [Loads] Respect UseDerefAtPointSemantics in isDerefAndAlignedPointer. (#123196)

If a pointer gets freed, it may not be dereferenceable any longer, even
though there is a dominating dereferenceable assumption. As first step,
only consider assumptions if the pointer value cannot be freed if
UseDerefAtPointSemantics is used.
