* config/s390/s390.c (struct machine_function): Use save_return_addr_p
as a general flag that the return address register needs to be saved,
not necessarily because of __builtin_return_addr (0).
(s390_split_branches): Remove TEMP_REG and TEMP_USED arguments,
remove special handling of zSeries machines.
(s390_optimize_prolog): Remove TEMP_USED argument, treat the return
register as a regular register on zSeries machines.
(s390_reorg): Adjust calls to s390_split_branches and
s390_optimize_prolog.
(s390_frame_info): On zSeries machines, do not assume the return
register is always used. Update regs_ever_live with current data
for the special registers.
(s390_emit_epilogue): Use save_return_addr_p to determine whether
the return register was saved.
* config/s390/s390.h (CONDITIONAL_REGISTER_USAGE): Do not mark
RETURN_REGNUM fixed on zSeries machines.
(REG_ALLOC_ORDER): Use RETURN_REGNUM last.
* config/s390/s390.md ("*doloop_si"): Handle branch overflow
via ahi-jgne pair on zSeries machines.
("*doloop_di"): Likewise.
("*doloop_di_long"): Remove.
