S/390: Don't fetch the return address early with ooo
We used to load the return address slot some time in advance. This
helped on older machines to resolve the data dependencies in time.
However, it is pointless on out of order CPUs. Disabled with that
patch.
gcc/ChangeLog:
2017-06-01 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.c (s390_emit_epilogue): Disable early return
address fetch for z10 or later.
