For the mem ops clustering logic, keep both old and new logic, guard
new logic by a flag. By default, the flag is disabled and the old logic will be
in place. When the flag is enabled, the new logic is triggered. The flag to
enable new logic is - `--amdgpu-enable-new-mem-ops-cluster-heuristic=true`.
