benchtests: Memory walking benchmark for memset
This benchmark is an attempt to eliminate cache effects from string benchmarks. The benchmark walks backward through a large memory area and sets different sizes of memory and alignments one at a time instead of looping around in the same memory area. This is a good metric to have alongside the simple memset benchmark (which is only really useful for smaller sizes) especially for larger sizes where the likelihood of the call being done only once is pretty high. * benchtests/bench-memset-walk.c: New file. * benchtests/Makefile (string-benchset): Add it.
