slomo:

The replacement for oil_cpu_get_flags() is 

  orc_target_get_default_flags(orc_target_get_by_name("sse"));

and testing against ORC_TARGET_SSE_SSE2, etc.  MMX is handled separately.

Just added a quick hack to orcc to push out performance data as part of the
test, so you can run tests/orc/volume and get this:

orc_process_int16:
  cycles (backup):   2.83178 0.0460488
  cycles (compiled): 0.938086 0.00306276
orc_process_int16_clamp:
  cycles (backup):   2.03946 0.00371835
  cycles (compiled): 0.774511 0.00130922
orc_process_int8:
  cycles (backup):   2.04956 0.00011869
  cycles (compiled): 0.712586 0.0015266
orc_process_int8_clamp:
  cycles (backup):   3.99119 0.00220664
  cycles (compiled): 0.609633 0.00128364
