/* Expected code generation for rlmi_test_1 is vrlwmi.
   Expected code generation for rlmi_test_2 is vrldmi.
   Expected code generation for vrlnm_test_1 is vrlwnm.
   Expected code generation for vrlnm_test_2 is vrldnm.
   Expected code generation for the others is more complex, because
   the second and third arguments are combined by a shift and OR,
   and because there is no splat-immediate doubleword.
    - For rlnm_test_1: vspltisw, vslw, xxlor, vrlwnm.
    - For rlnm_test_2: xxspltib, vextsb2d, vsld, xxlor, vrldnm.
   There is a choice of splat instructions in both cases, so we
   just check for "splt".  */
