Starting with z13, vector registers can also occur as argument registers. Thus the passed input/output register structs for la_s390_[32|64]_gnu_plt[enter|exit] functions should reflect those new registers. This patch extends these structs La_s390_regs and La_s390_retval and adjusts _dl_runtime_profile() to handle those fields in case of running on a z13 machine. ChangeLog: * sysdeps/s390/bits/link.h: (La_s390_vr) New typedef. (La_s390_32_regs): Append vector register lr_v24-lr_v31. (La_s390_64_regs): Likewise. (La_s390_32_retval): Append vector register lrv_v24. (La_s390_64_retval): Likeweise. * sysdeps/s390/s390-32/dl-trampoline.h (_dl_runtime_profile): Handle extended structs La_s390_32_regs and La_s390_32_retval. * sysdeps/s390/s390-64/dl-trampoline.h (_dl_runtime_profile): Handle extended structs La_s390_64_regs and La_s390_64_retval.
