Faster memset on x64 hjl/2.17/memset
This implementation speed up memset in several ways. First is avoiding expensive computed jump. Second is using fact that arguments of memset are most of time aligned to 8 bytes. Benchmark results on: kam.mff.cuni.cz/~ondra/benchmark_string/memset_profile_result27_04_13.tar.bz2 (cherry picked from commit b2b671b677d92429a3d41bf451668f476aa267ed)
