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

[robert lytton]

  Hi Renato,

  For some reason I am getting a hash of: 71688e3f0dfde5f7a36e30b155d09d32
  I get the same image for xcore and my native clang+llvm-3.3-Ubuntu-13.04-x86_64-linux-gnu compiler.
  I attach the image for you to compare with your output. {F48555}

  Robert
