This patch makes use of the vector permute double immediate
instruction for constant permute vectors.

gcc/ChangeLog:

* config/s390/s390.c (expand_perm_with_vpdi): New function.
(vectorize_vec_perm_const_1): Call expand_perm_with_vpdi.
* config/s390/vector.md (*vpdi1<mode>, @vpdi1<mode>): Enable a
parameterized expander.
(*vpdi4<mode>, @vpdi4<mode>): Likewise.

gcc/testsuite/ChangeLog:
