S/390: Implement -mnop-mcount
On i386 the profiler call sequence always consists of 1 call
instruction, so -mnop-mcount generates a single nop with the same
length as a call. For S/390 longer sequences may be used in some
cases, so -mnop-mcount generates the corresponding amount of nops.

* config/s390/s390.c (s390_function_profiler): Generate nops
instead of profiler call sequences.
* config/s390/s390.opt: Add the new option.
