Because it is never dereferenced.  We only create memory tags for
dereferenced pointers.  The aliaser decides that it is
pointless to compute aliasing information for a non-dereferenced
pointer, because there are no loads/stores to the pointed-to
memory.

Is this a problem for your analysis?  Do you need points-to
information for non-dereferenced pointers as well?  That is
slightly different than the alias information gathered for memory
tags.
