Evaluate the binary64 dilogarithm series with Estrin's scheme Replace the nine dependent (complex) multiply-adds of the Bernoulli series by Estrin's scheme in v = u^2. The worst relative error over the test arguments is unchanged (5.5e-16); a pinned single-core run drops from 47 to 40 ns at 0.3+0.1i and from 79 to 75 ns averaged over 1,024 points.
