Benchmark scene (povray --benchmark) using Povray 3.6 on a Core i5 3317U @ 1.7
GHz on Ubuntu 12.04 (64-bit). I'd love to try Povray 3.7, but I can't get it to
compile with either open64 or icc, which is too bad since icc give a nice 17%
performance increase over gcc.

        icc 13.1.1, -xCORE-AVX-I
        234.80 pps; 138.12 pps/GHz
  Parse Time:    0 hours  0 minutes  0 seconds (0 seconds)
  Photon Time:   0 hours  0 minutes 14 seconds (14 seconds)
  Render Time:   0 hours 10 minutes 14 seconds (614 seconds)
  Total Time:    0 hours 10 minutes 28 seconds (628 seconds)

        gcc 4.8, -march=core-avx-i
        203.1 pps; 119.47 pps/GHz
  Parse Time:    0 hours  0 minutes  1 seconds (1 seconds)
  Photon Time:   0 hours  0 minutes 17 seconds (17 seconds)
  Render Time:   0 hours 11 minutes 48 seconds (708 seconds)
  Total Time:    0 hours 12 minutes  6 seconds (726 seconds)

        open64 5.0, -march=wolfdale
        201.99 pps; 118.82 pps/GHz
  Parse Time:    0 hours  0 minutes  0 seconds (0 seconds)
  Photon Time:   0 hours  0 minutes 16 seconds (16 seconds)
  Render Time:   0 hours 11 minutes 54 seconds (714 seconds)
  Total Time:    0 hours 12 minutes 10 seconds (730 seconds)

For Icc on core i7 with 3.7, I did it like that:
