bpf, tests: add tests for optmized memmove replacement
Extend the builtin test suite and add __bpf_memmove() tests along the
existing __bpf_mem{set,cpy,cmp}() ones. The memmove is split into four
subtests: 1) same (non-overlapping) memcpy test just with memmove, 2)
overlapping with dst < src, 3) overlapping with dst == src, 4) overlapping
with dst > src. Also improve / only use barrier_data() where it makes
sense.
