new patch

This new patch changes one little thing dealing with how with indirect
references are handled in dr_analyze_indices.  If we already inserted indices
for array references and the indirect reference is not changing, dnn't add that
index of 0.  This lets us get rid of the chang in build_classic_dist_vector_1
which I was worried about.
