Yes. Look for places where MEM_COPY_ATTRIBUTES is used but
MEM_ALIAS_SET is not. They should represent places where the
resulting memory doesn't have the same type as the original memory.
(For example, the new MEM might not point at the same location as the
old MEM, or might be wider.)
But in that case, you have to set *some* value for MEM_ALIAS_SET, right?
