/* This test verifies that a vector extract operand properly has its
   lane changed by the swap optimization.  Element 2 of LE corresponds
   to element 1 of BE.  When doublewords are swapped, this becomes
   element 3 of BE, so we need to shift the vector left by 3 words
   to be able to extract the correct value from BE element zero.  */
