benchtests: Add benches for memset with 0 value
memset with zero as the value to set is by far the majority value (99%+ for Python3 and GCC). Add bench-memset-zero-large.c, bench-memset-zero-walk.c and bench-memset-zero.c to measure memset implementations for zeroing. Reviewed-by: Sunil K Pandey <skpgkp2@gmail.com>
