S/390: Fix vec_sldw builtin

The builtin was wired up to the wrong pattern.  Fixed with this patch.

gcc/ChangeLog:

2019-05-17  Andreas Krebbel  <krebbel@linux.ibm.com>

	* config/s390/s390-builtins.def (s390_vec_sldw_*): Use the
	vec_sldw insn pattern.

gcc/testsuite/ChangeLog:

2019-05-17  Andreas Krebbel  <krebbel@linux.ibm.com>

	* gcc.target/s390/zvector/vec-sldw.c: New test.
