[PATCH] Implement sin/cos for sphereflake test-suite

[robert lytton]

  Hi Renato,

  Sorry, should have looked more carefully re small/large.

  Could you change:
    std::cerr << count << " spheres.";
  to:
    std::cout << count << " spheres.";
  to make the output deterministic on all targets.

  Otherwise, LGTM.

  Robert
