I would much prefer an "enable" flag. Otherwise you have to parse a double negative to understand what `-disable-thing=false` means.

static cl::opt<bool> EnableDiffBasePtrMemClustering(
    "amdgpu-disable-diff-baseptr-mem-clustering",
    cl::desc("Disable clustering memory ops with different base pointers"),
    cl::init(true), cl::Hidden);
