This enables the following tests which rely on instruction vperm which
is available since z13 with the initial vector support.
testsuite/gcc.dg/vect/vect-bswap16.c
42:/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target
{ vect_bswap || sse4_runtime } } } } */
testsuite/gcc.dg/vect/vect-bswap32.c
42:/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target
{ vect_bswap || sse4_runtime } } } } */
testsuite/gcc.dg/vect/vect-bswap64.c
42:/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target
{ vect_bswap || sse4_runtime } } } } */
Ok for mainline?
