If a class's first data member is an instance of an empty class, then an
assertion in the PrettyClassLayoutGraphicalDumper would fail. The
storage is reserved, but it's not marked as in use.
As far as I understand, it's the assertion that's faulty, so I removed it
and updated the nearby comment.
Found by running llvm-pdbutil against its own PDB, and this assertion would
fail on HashAdjusters, which is a HashTable whose first data member is a
TraitsT, which is a PdbHashTraits<T>, which is an empty struct. (The struct
has a specialization for uint32_t, but that specialization doesn't apply
here because the T is actually ulittle32_t.)

Static data members were causing a problem because I mistakenly
assumed all members would affect a class's layout and so the
Layout member would be non-null.

This is to reflect the evolving nature of the tool as being
useful for more than just dumping PDBs, as it can do many other
things.
