S/390: Don't emit prefetch instructions for clrmem
gcc/ChangeLog:
2018-07-31 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/s390.c (s390_expand_setmem): Make the unrolling to
depend on whether prefetch instructions will be emitted or not.
Use TARGET_SETMEM_PFD for checking whether prefetch instructions
will be emitted or not.
* config/s390/s390.h (TARGET_SETMEM_PREFETCH_DISTANCE)
(TARGET_SETMEM_PFD): New macros.
gcc/testsuite/ChangeLog:
