S/390: Change 2-byte NOPs
The following patch changes "nopr %r7" to "nopr %r0" which is
advantageous from a hardware perspective. It will only be emitted for
hotpatching and should not impact normal code.
gcc/ChangeLog:
2017-03-06 Robin Dapp <rdapp@linux.vnet.ibm.com>
* config/s390/s390.c (s390_asm_output_function_label): Use nopr %r0.
