You can add a comment to the PR and tag @pytorchbot with the following commands:
# ciflow rerun, "ciflow/default" will always be added automatically
@pytorchbot ciflow rerun

# ciflow rerun with additional labels "-l <ciflow/label_name>", which is equivalent to adding these labels manually and trigger the rerun
@pytorchbot ciflow rerun -l ciflow/scheduled -l ciflow/slow

Summary:
Pull Request resolved: #65504

We should be able to borrow a Tuple from an IValue without incurring refcount bumps.
ghstack-source-id: 142065833

Test Plan:
Added test coverage.

Profiled static runtime on the local_ro net for ctr_mobile_feed. Inclusive time spent in VarTupleUnpack decreased about 0.3%, which roughly matches with the 0.36% of runtime that was previously spent in IValue::toTuple().
