SimpleNonOwningHashTable causes incorrect results while HashBuild with unique keys

[bagrorg]

If in the file hash_build.cpp replace the construction of host_src with filling with random keys with filling with keys 0,1..., buf_size, then when running with the following parameters, the output will potentially output incorrect results.

std::vector<uint32_t> host_src;
for (int i = 0; i < buf_size; i++) {
  host_src.push_back(i);
}

DWARF_BENCH_ROOT is set to /dwarf_bench/build

Moreover, when the range of randomly generated keys increases, incorrect results also occur

@bagrorg, is this obsolete now?
