s390x: Mark VRs as clobbered by helper calls

According to the s390x ABI, all vector registers are call-clobbered
(except for their portions that overlap with the call-saved FPRs).  But
the s390x backend doesn't mark them as such when determining the register
usage of helper call insns.

Fix this in s390_insn_get_reg_usage when handling S390_INSN_HELPER_CALL.
