For reference this is the speedup of simple-raytracer compiled with cg_clif:

Benchmark #1: raytracer_cg_clif_x64_post
  Time (mean ± σ):      8.365 s ±  0.047 s    [User: 8.357 s, System: 0.008 s]
  Range (min  max):    8.297 s   8.470 s    10 runs

Benchmark #2: ./raytracer_cg_clif_x64_pre
  Time (mean ± σ):      8.492 s ±  0.052 s    [User: 8.485 s, System: 0.007 s]
  Range (min  max):    8.425 s   8.600 s    10 runs

Summary
  'raytracer_cg_clif_x64_post' ran
    1.02 ± 0.01 times faster than './raytracer_cg_clif_x64_pre'

TODO relating to PR2149: change the lowering for Opcode::AtomicStore so as to use lower_to_amode rather than forcing the amode to be of the form 0(reg).
