It seems your comment is still valid, i.e. we could use the helper function to
look for an address-of expression. I refactored the helper so it can be used
easily in `IsPtrBufferSafe` (see last commit), but I think the change to
`isPtrBufferSafe` should be in a separate PR in case it accidentally changes
behavior / needs to be rolled back.
