Bump up the runtime for "short" benchmarks
Some benchmarks with a very short runtime show significantly different results across runs on Aarch64 - up to tens of percents. Increasing the runtime to 100ms+ makes the deviation under 5%. Tested on Aarch64 and x86-64. Reviewed-by: Carlos O'Donell <carlos@redhat.com> * benchtests/bench-memccpy.c: Replace INNER_LOOP_ITERS with INNER_LOOP_ITERS_LARGE. * benchtests/bench-memchr.c: Likewise. * benchtests/bench-rawmemchr.c: Likewise. * benchtests/bench-strcat.c: Likewise. * benchtests/bench-strchr.c: Likewise. * benchtests/bench-string.h: Likewise. * benchtests/bench-strlen.c: Likewise. * benchtests/bench-strncpy.c: Likewise. * benchtests/bench-strnlen.c: Likewise.
