debug-only not working for loop interchange pass

[shanksjoe]

$ cat test.c 
void test(float **indices, float init_i, int M, int K) {
  for (int j = 0; j < K; ++j) {
    for (int i = 0; i < M; ++i) {
      indices[i][j] = init_i + i;
    }
  }
}
$ clang -O2 -S test.c -emit-llvm -mllvm -enable-loopinterchange=true -mllvm -debug-only=loop-interchange

There is not oputput.

Can you try -floop-interchange: https://godbolt.org/z/7Th93363b

#125830 would cause it. It appears that the -enable-loopinterchange is no longer referenced when clang is used.
