S390: Add hwcaps value for vector facility.
The HWCAP_S390_VX flag in hwcap field of auxiliary vector indicates if the vector facility is available and the kernel is aware of it. This can be tested with LD_SHOW_AUXV=1 <prog>. Currently it does not show te, because it was not incremented by commit "S/390: Add hwcap value for transactional execution.". Thus _DL_HWCAP_COUNT is incremented by two. ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_platforms): Add vector flag. * sysdeps/s390/dl-procinfo.h: Add vector capability. * sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VX): Define.
