https://github.com/llvm/llvm-project/blob/master/llvm/lib/IR/Metadata.cpp#L716 is where the auto-detection of self-references is:

  // Drop uniquing for self-reference cycles and deleted constants.
  if (New == this || (!New && Old && isa<ConstantAsMetadata>(Old))) {
    if (!isResolved())
      resolve();
    storeDistinctInContext();
    return;
  }
