  50    Expected code generation for rlmi_test_2 is vrldmi.
  51    Expected code generation for vrlnm_test_1 is vrlwnm.
  52    Expected code generation for vrlnm_test_2 is vrldnm.
  53    Expected code generation for the others is more complex, because
  54    the second and third arguments are combined by a shift and OR,
  55    and because there is no splat-immediate doubleword.
  56     - For rlnm_test_1: vspltisw, vslw, xxlor, vrlwnm.
  57     - For rlnm_test_2: xxspltib, vextsb2d, vsld, xxlor, vrldnm.
  58    There is a choice of splat instructions in both cases, so we
  59    just check for "splt".  */
