I was thinking of three analytic benchmarks: SOLKY, SOLCX, and the
circular inclusion under shear.  These can be extended to 3D and
rotated so that they exercise all of the 3D parts.  The only true 3D
benchmark I can think of is the falling Stokes sphere.  Are there
other analytic benchmarks I should be looking at?
