Ensure benchmarks take less than 10 seconds on older, slower cores and more than 0.5 seconds on fast cores.

Add bench-memset-zero-large.c, bench-memset-zero-walk.c and bench-memset-zero.c to measure memset implementations for zeroing.

Remove simplistic byte-oriented versions with faster generic implementations. Remove bcopy/bzero benchmarks (bcopy/bzero are obsolete and never emitted by compilers). Remove builtin versions of memcpy, memset and strlen.
