/* The expansion for vector character multiply introduces a vperm operation.
   This tests that changing the vperm mask allows us to remove all swaps
   from the generated code.  It is a duplicate of swaps-p8-21.c, except
   that it applies the large code model, which requires an extra indirection
   in the load of the constant mask.  */
