This check is redundant because if inner_most_id == nullptr, it must has max_dims==0, which is skipped in previous lines:

  // If everything is zero dim tensors, just return.
  if (max_dims == 0) {
    return;
  }

[NVFuser] Upstream push 0714
f686d82 
Syncing nvfuser devel branch to upstream master. https://github.com/csarofeen/pytorch/

Code changes includes:

- codegen improvements:
  1. Indexing refactor -> Remove reference tensor in predicate indexing logic
  2. MMA Rfactor support for cross-warp and cross-CTA split on K dimension
  3. Grouping grid allreduces across iterations
  4. Swizzle op formulation for non-affine swizzles
  5. Use scheduler_utils to cache inputs and outputs in schedulePointwise
- scheduler refactor
  1. New compute at interface
- transformation propagation refactor on MaxInfoSpanningTree
  1. Added sibling path that is required to generate consistent replay for some cases where `MaxInfoSpanningTree` is used with a selector.
  2. Optimization to skip Transform propagator
  3. SpanningTreePrinter for debugging
- parser update
  1. Fixes `div`
  2. Added `_to_copy`
  3. Broadcast in dim with expand to support expanding to concrete size
  4. Dropout prob extremal patch
- executor patch on caching strides for output allocation
