this symbol and signal to the caller that no further processing is
needed. But we don't have the index for this hash-table entry. We
rely here on that the current entry is the first hash-entry with NULL,
which seems brittle. Also, iterating over the hash-table to find that
entry is a linear operation on the number of symbols in this input
file, and this function should take constant time, so that's not good
too. Only comfort is that DataLabel references should only be found in
hand-written assembly code and thus be rare. FIXME: Talk maintainers
